Error cache miss php - Исправление ошибок и поиск оптимальных решений проблем

**Some background: Credit goes to bruce (sqlwork.com) for his excellent explanation.

This web page requires data that you entered earlier in order to be properly displayed. You can send this data again, but by doing so you will repeat any action this page previously performed. Press Reload to resend that data and display this page.

Because of the sloppy coding practices of web developers browsers were forced to add this message. the scenario is as follows:

1) user fills in form and submits (posts form)
2) the server process the post data and responds with a new page (confirm) marked as not cacheable
3) the user navigates to a new page.
4) the user press back:

for the the browser to display the page in step 2, because its marked no-cache, it must request it from the server, in other words do the repost of the data (do step 1). here is were the sloppy coding came in, if this was an credit card charge, and repost detection was not on the server, the card is charged twice. this was (is) so common a problem, that the browsers had to detect this and warn the users.

the best fix is in step two, the server sends a redirect to the confirm page. then when the user accesses the confirm via history or back, its a get request, not a post request and will not show the warning.

note: webform’s postback model lends itself to this problem. also avoid server transfers.

My solution

$_SESSION[‘home’] used to store any errors on home page.

$_SESSION[‘tempEmail’] used to echo value on php form.

Note: Use one unique session variable for each page that has a HTML form for error handling and also any session variable for each value that is echoed on HTML form.

<?php
session_start(); 

//Initialize variables not initialized without overwriting previously set variables.
if(!isset($_SESSION['home'])) {
$_SESSION['home']="";
$_SESSION['tempEmail']="";
}

Optional — If logged in, assign email address to the $_SESSION[‘tempEmail’] variable (if not previously done) to pre-fill HTML form.

if(isset($_POST['Submit'])){

---your code---


    //Error message(s) examples
    $_SESSION['home'] = "Email and Password do not match, please try again.";
    header("Location: " . $_SERVER['REQUEST_URI']);

    $_SESSION['home'] = "Email address format is invalid.  Please recheck.";
    header("Location: " . $_SERVER['REQUEST_URI']);

    //success
    unset ($_SESSION['home']); //optional, unset to clear form values.
    header ("location: nextpage.php"); 
             ---or---
    header("Location: " . $_SERVER['REQUEST_URI']);  //re-post to same page with the $_SESSION['home'] success message.   
}
?>



<body>

Error box

<span><strong class="error"><?php echo $_SESSION['home'] ?></strong></span>

HTML form

<form action="#" name="loginform" method="post" >
    <input type="text" name="userEmail" maxlength="50" title="Enter Your email" autocomplete="off" value="<?php echo htmlspecialchars($_SESSION['tempEmail']); ?>" placeholder="enter email" required/>
    <input type="submit" name="Submit" value="Submit">
</form>

</body>

Not recommended to use on payment page,see discussion above. Tested in Firefox, Chrome, Safari, and IE9. The annoying messages are gone when using back button. Ensure that output buffering is turned «on» in your php script or php.ini to avoid header warnings. You can check your php.ini file for the following;

output_buffering=On

Пользователи могут столкнуться с ошибкой ERR_CACHE_MISS, сообщающей о повторной отправке формы. Обычно это означает, что просматриваемая веб-страница требует предоставления данных для продолжения. Иногда, когда вы уже ввели данные, их нужно ввести заново или будут использованы старые. Если эта ошибка повторяется, это означает, что проблема в вашем текущем браузере. Некоторые элементы в кеше могут быть непригодными для использования или некоторые конфигурации могут быть настроены неправильно.

Мы можем выполнить некоторые проверки вашего браузера, чтобы убедиться, что эта ошибка исходит от вас. Если к концу устранения неполадок вы определили, что проблема не в вашем браузере, это означает, что эта ошибка возникла на стороне сервера веб-сайта, и вы ничего не можете сделать, пока разработчики не исправят ее там.

Удалите строку кэша из заголовка PHP

В «Заголовке» есть специальная строка, если вы открыли форму в PHP-коде, эта строка сообщает браузеру не кэшировать данные с сайта. Поэтому на этом этапе мы удалим эту строку. Для этого:

Заголовок в коде PHP обычно выглядит следующим образом.
```
 header ('Cache-Control: no  -store, no-cache, must-revalidate, max-age = 0 '); 
```
Мы должны удалить « no-store , »Так, чтобы она выглядела как следующая строка.
```

всё правильно. значит ресурс передавался в ответ на POST-запрос. обычно после отправки формы делают редирект с GET-запросом и тогда обновление или шаг назад уже не вызывают таких проблем.

Google Chrome is one of the most popular and reliable web browsers out there, but it isn’t without fault. There are a handful of common issues you might encounter while using it, including the ‘ERR_CACHE_MISS’ error message.

If you’ve come across this message, chances are the browser is also asking you to re-enter or submit some information. While this error can be confusing and frustrating, it’s also entirely fixable.

There are a handful of quick, easy methods you can use to resolve this error message, and successfully reach the site you’re trying to visit.

In this post, we’ll explain what ‘ERR_CACHE_MISS’ means and discuss some of its common causes. Then we’ll walk you through several methods you can use to fix it.

Let’s get started!

What Does ‘ERR_CACHE_MISS’ Mean?

There are a handful of popular error messages you might come across when using Chrome. These include issues like ERR_QUIC_PROTOCOL_ERROR and ERR_SSL_OBSOLETE_VERSION.

Another error that Chrome users frequently encounter is the ‘ERR_CACHE_MISS’ message:

The ERR_CACHE_MISS Message in Google Chrome

From the name, it’s clear that this error is related to caching. More specifically, there are a variety of reasons you might be seeing this message, including:

Your browser is unable to obtain cache files from the site you’re trying to access.
There are bugs, corruptions, or inefficiencies in your browser, browser settings, or browser extensions.
The website you’re trying to visit has incorrect coding or PHP issues.

If you’re a developer, you may encounter this message if you’re using the wrong codes to test an application or website, either on Android or another OS.

As a user, you could encounter it when trying to access just about any website, even highly-popular ones such as Facebook.

It’s worth noting that while this problem is almost entirely exclusive to Chrome, some users have reported running into similar issues in Firefox. More specifically, in versions of Firefox 32 and above, the message reads as “Document Expired”.

However, most messages include a “Confirm Form Resubmission” message or prompt. This usually occurs when a Chrome user is completing or submitting a form and uses the back/forward buttons too often or too quickly.

Alternatively, you can also press the F5 key on your keyboard. If you still see the error message, it’s safe to assume that your network connectivity was not the source of the issue, and it’s time to move on to the next method.

2. Update Your Browser

If you’re using an old or outdated version of Chrome, it’s a smart idea to upgrade to the latest version. This can help to eliminate any incompatibility issues or inefficiencies that might be contributing to the ‘ERR_CACHE_MISS’ error message.

To update your browser, open a new window and then navigate to Settings > About Chrome:

About the Chrome browser

On this page, you’ll see whether you’re using the latest version of the browser. If you’re not, there will be an option to Update Chrome.

Follow the prompts, then restart your browser and try to access the web page again.

3. Clear Your Browser Data

If your browser has accumulated corrupted files in your cache, it may result in the error message you’re seeing now. Therefore, the next step you should take in your attempt to resolve the problem is to clear your browser data.

To do this, go back to your Chrome settings menu. Hover over More tools, and then in the menu panel that opens, select Clear browsing data:

Clearing Chrome browser data

In the window that appears next, make sure all three options (Browsing history, Cookies and other site data, and Cached images and files) are selected. Hit the Clear data button:

The Google Chrome Clear Data option

Once you clear the data, refresh the browser.

Hopefully, you’ll no longer see the ERR_CACHE_MISS message. If you do, it’s time for the next method.

4. Disable Your Browser Extensions

Another potential issue that may be causing the ‘ERR_CACHE_MISS’ error is that one of the extensions you have installed is corrupted, or is interfering with Chrome’s ability to connect to and load the web page.

To determine whether this is the problem, the best course of action is to disable all of your browser extensions.

To locate these, go to your Chrome settings, hover over the More tools option, and then select Extensions:

Google Chrome extensions

This will bring you to the Extensions page, where you can see any and all extensions that are installed. One by one, go through them and toggle the disable option for each:

The option to disable a Chrome extension

We recommend starting with any ad blocking extensions, as these are most likely to be the culprit. Try refreshing your browser after you disable each extension, to see if the error resolves itself.

If it does, you’ll be able to pinpoint (and remove) the problematic extension. If not, your extensions probably aren’t to blame.

5. Reset Your Network Settings

Problems with your network settings can also cause the ‘ERR_CACHE_MISS’ message. To resolve that, you can try resetting those settings.

The easiest way to do this is through your Command Window, which you can open by clicking on the Windows icon, typing “cmd” into the search field, and then selecting Run as Administrator in the Command Prompt app:

The command prompt in Windows

With the Command Prompt window open, type in the following and press Enter after each line:

ipconfig/release

ipconfig/all

ipconfig/flushdns

ipconfig/renew

netsh int ip set dns

netsh winsock reset

ipconfig renew

ipconfig renew

On macOS, you can do this through the Terminal app. Navigate to Finder > Applications > Utilities:

The Applications folder on macOS

Once you open the Utilities folder, locate and open the Terminal app:

macOS Terminal application in the Utilities folder

In the Terminal window, type in the following commands and press Enter after each one:

dscacheutil -flushcache

sudo killall -HUP mDNSResponder

Restart your computer and open a new browser window. Your network settings will revert to their defaults, which will hopefully keep you from seeing the ‘ERR_CACHE_MISS’ error again.

6. Reset Your Browser Settings

If your network settings aren’t the issue, the problem may lie with your browser settings. Therefore, the next logical step is to reset those settings.

To do this, go to Settings, followed by Advanced > Reset settings:

Chrome Advanced Settings

A prompt window will open. Again, click on the Reset option:

Resetting settings in Chrome

You can also access the reset settings page by going to chrome://settings/resetProfileSettings.

Finally, restart your browser and try to access the web page again. Hopefully, you will no longer see the ’ERR_CACHE_MISS’ message. However, if you do, it’s time to move on to the last method.

7. Disable Your Cache System

At this point, you have hopefully resolved the ‘ERR_CACHE_MISS’ error message in Chrome. If not, there’s one last solution you can try to fix the problem: disabling your caching system.

Doing this requires you to use the Chrome DevTools. These can be found in the browser’s settings, under More tools > Developer tools. Just be sure to open the DevTools on the browser page that’s displaying the error message.

Then, under the Network section, select the option to Disable Cache:

Disabling the Chrome cache

Once you check this item, reload the web page. You should no longer see the ‘ERR_CACHE_MISS’ message.

Caching Interface

Caching is a common way to improve the performance of any project, making
caching libraries one of the most common features of many frameworks and
libraries. This has lead to a situation where many libraries roll their own
caching libraries, with various levels of functionality. These differences are
causing developers to have to learn multiple systems which may or may not
provide the functionality they need. In addition, the developers of caching
libraries themselves face a choice between only supporting a limited number
of frameworks or creating a large number of adapter classes.

A common interface for caching systems will solve these problems. Library and
framework developers can count on the caching systems working the way they’re
expecting, while the developers of caching systems will only have to implement
a single set of interfaces rather than a whole assortment of adapters.

The key words «MUST», «MUST NOT», «REQUIRED», «SHALL», «SHALL NOT», «SHOULD»,
«SHOULD NOT», «RECOMMENDED», «MAY», and «OPTIONAL» in this document are to be
interpreted as described in RFC 2119.

Goal

The goal of this PSR is to allow developers to create cache-aware libraries that
can be integrated into existing frameworks and systems without the need for
custom development.

Definitions

Calling Library — The library or code that actually needs the cache
services. This library will utilize caching services that implement this
standard’s interfaces, but will otherwise have no knowledge of the
implementation of those caching services.
Implementing Library — This library is responsible for implementing
this standard in order to provide caching services to any Calling Library. The
Implementing Library MUST provide classes which implement the
CacheCacheItemPoolInterface and CacheCacheItemInterface interfaces.
Implementing Libraries MUST support at minimum TTL functionality as described
below with whole-second granularity.
TTL — The Time To Live (TTL) of an item is the amount of time between
when that item is stored and it is considered stale. The TTL is normally defined
by an integer representing time in seconds, or a DateInterval object.
Expiration — The actual time when an item is set to go stale. This is
typically calculated by adding the TTL to the time when an object is stored, but
may also be explicitly set with DateTime object. An item with a 300 second TTL
stored at 1:30:00 will have an expiration of 1:35:00. Implementing Libraries MAY
expire an item before its requested Expiration Time, but MUST treat an item as
expired once its Expiration Time is reached. If a calling library asks for an
item to be saved but does not specify an expiration time, or specifies a null
expiration time or TTL, an Implementing Library MAY use a configured default
duration. If no default duration has been set, the Implementing Library MUST
interpret that as a request to cache the item forever, or for as long as the
underlying implementation supports.
Key — A string of at least one character that uniquely identifies a
cached item. Implementing libraries MUST support keys consisting of the
characters A-Z, a-z, 0-9, _, and . in any order in UTF-8 encoding and a
length of up to 64 characters. Implementing libraries MAY support additional
characters and encodings or longer lengths, but must support at least that
minimum. Libraries are responsible for their own escaping of key strings
as appropriate, but MUST be able to return the original unmodified key string.
The following characters are reserved for future extensions and MUST NOT be
supported by implementing libraries: {}()/@:
Hit — A cache hit occurs when a Calling Library requests an Item by key
and a matching value is found for that key, and that value has not expired, and
the value is not invalid for some other reason. Calling Libraries SHOULD make
sure to verify isHit() on all get() calls.
Miss — A cache miss is the opposite of a cache hit. A cache miss occurs
when a Calling Library requests an item by key and that value not found for that
key, or the value was found but has expired, or the value is invalid for some
other reason. An expired value MUST always be considered a cache miss.
Deferred — A deferred cache save indicates that a cache item may not be
persisted immediately by the pool. A Pool object MAY delay persisting a deferred
cache item in order to take advantage of bulk-set operations supported by some
storage engines. A Pool MUST ensure that any deferred cache items are eventually
persisted and data is not lost, and MAY persist them before a Calling Library
requests that they be persisted. When a Calling Library invokes the commit()
method all outstanding deferred items MUST be persisted. An Implementing Library
MAY use whatever logic is appropriate to determine when to persist deferred
items, such as an object destructor, persisting all on save(), a timeout or
max-items check or any other appropriate logic. Requests for a cache item that
has been deferred MUST return the deferred but not-yet-persisted item.

Data

Implementing libraries MUST support all serializable PHP data types, including:

Strings — Character strings of arbitrary size in any PHP-compatible encoding.
Integers — All integers of any size supported by PHP, up to 64-bit signed.
Floats — All signed floating point values.
Boolean — True and False.
Null — The actual null value.
Arrays — Indexed, associative and multidimensional arrays of arbitrary depth.
Object — Any object that supports lossless serialization and
deserialization such that $o == unserialize(serialize($o)). Objects MAY
leverage PHP’s Serializable interface, __sleep() or __wakeup() magic methods,
or similar language functionality if appropriate.

All data passed into the Implementing Library MUST be returned exactly as
passed. That includes the variable type. That is, it is an error to return
(string) 5 if (int) 5 was the value saved. Implementing Libraries MAY use PHP’s
serialize()/unserialize() functions internally but are not required to do so.
Compatibility with them is simply used as a baseline for acceptable object values.

If it is not possible to return the exact saved value for any reason, implementing
libraries MUST respond with a cache miss rather than corrupted data.

Key Concepts

Pool

The Pool represents a collection of items in a caching system. The pool is
a logical Repository of all items it contains. All cacheable items are retrieved
from the Pool as an Item object, and all interaction with the whole universe of
cached objects happens through the Pool.

Items

An Item represents a single key/value pair within a Pool. The key is the primary
unique identifier for an Item and MUST be immutable. The Value MAY be changed
at any time.

Error handling

While caching is often an important part of application performance, it should never
be a critical part of application functionality. Thus, an error in a cache system SHOULD NOT
result in application failure. For that reason, Implementing Libraries MUST NOT
throw exceptions other than those defined by the interface, and SHOULD trap any errors
or exceptions triggered by an underlying data store and not allow them to bubble.

An Implementing Library SHOULD log such errors or otherwise report them to an
administrator as appropriate.

If a Calling Library requests that one or more Items be deleted, or that a pool be cleared,
it MUST NOT be considered an error condition if the specified key does not exist. The
post-condition is the same (the key does not exist, or the pool is empty), thus there is
no error condition.

Interfaces

CacheItemInterface

CacheItemInterface defines an item inside a cache system. Each Item object
MUST be associated with a specific key, which can be set according to the
implementing system and is typically passed by the CacheCacheItemPoolInterface
object.

The CacheCacheItemInterface object encapsulates the storage and retrieval of
cache items. Each CacheCacheItemInterface is generated by a
CacheCacheItemPoolInterface object, which is responsible for any required
setup as well as associating the object with a unique Key.
CacheCacheItemInterface objects MUST be able to store and retrieve any type of
PHP value defined in the Data section of this document.

Calling Libraries MUST NOT instantiate Item objects themselves. They may only
be requested from a Pool object via the getItem() method. Calling Libraries
SHOULD NOT assume that an Item created by one Implementing Library is
compatible with a Pool from another Implementing Library.

<?php

namespace PsrCache;

/**
 * CacheItemInterface defines an interface for interacting with objects inside a cache.
 */
interface CacheItemInterface
{
    /**
     * Returns the key for the current cache item.
     *
     * The key is loaded by the Implementing Library, but should be available to
     * the higher level callers when needed.
     *
     * @return string
     *   The key string for this cache item.
     */
    public function getKey();

    /**
     * Retrieves the value of the item from the cache associated with this object's key.
     *
     * The value returned must be identical to the value originally stored by set().
     *
     * If isHit() returns false, this method MUST return null. Note that null
     * is a legitimate cached value, so the isHit() method SHOULD be used to
     * differentiate between "null value was found" and "no value was found."
     *
     * @return mixed
     *   The value corresponding to this cache item's key, or null if not found.
     */
    public function get();

    /**
     * Confirms if the cache item lookup resulted in a cache hit.
     *
     * Note: This method MUST NOT have a race condition between calling isHit()
     * and calling get().
     *
     * @return bool
     *   True if the request resulted in a cache hit. False otherwise.
     */
    public function isHit();

    /**
     * Sets the value represented by this cache item.
     *
     * The $value argument may be any item that can be serialized by PHP,
     * although the method of serialization is left up to the Implementing
     * Library.
     *
     * @param mixed $value
     *   The serializable value to be stored.
     *
     * @return static

     */
    public function set($value);

    /**
     * Sets the expiration time for this cache item.
     *
     * @param DateTimeInterface|null $expiration
     *   The point in time after which the item MUST be considered expired.

     *   the value should be stored permanently or for as long as the
     *   implementation allows.
     *
     * @return static
     *   The called object.
     */
    public function expiresAt($expiration);

    /**
     * Sets the expiration time for this cache item.
     *
     * @param int|DateInterval|null $time
     *   The period of time from the present after which the item MUST be considered
     *   expired. An integer parameter is understood to be the time in seconds until
     *   expiration. If null is passed explicitly, a default value MAY be used.
     *   If none is set, the value should be stored permanently or for as long as the
     *   implementation allows.
     *
     * @return static
     *   The called object.
     */
    public function expiresAfter($time);

}

CacheItemPoolInterface

The primary purpose of CacheCacheItemPoolInterface is to accept a key from the
Calling Library and return the associated CacheCacheItemInterface object.
It is also the primary point of interaction with the entire cache collection.
All configuration and initialization of the Pool is left up to an Implementing
Library.

<?php

namespace PsrCache;

/**
 * CacheItemPoolInterface generates CacheItemInterface objects.
 */
interface CacheItemPoolInterface
{
    /**
     * Returns a Cache Item representing the specified key.
     *
     * This method must always return a CacheItemInterface object, even in case of
     * a cache miss. It MUST NOT return null.
     *
     * @param string $key
     *   The key for which to return the corresponding Cache Item.
     *
     * @throws InvalidArgumentException
     *   If the $key string is not a legal value a PsrCacheInvalidArgumentException
     *   MUST be thrown.
     *
     * @return CacheItemInterface
     *   The corresponding Cache Item.
     */
    public function getItem($key);

    /**
     * Returns a traversable set of cache items.
     *
     * @param string[] $keys
     *   An indexed array of keys of items to retrieve.
     *
     * @throws InvalidArgumentException
     *   If any of the keys in $keys are not a legal value a PsrCacheInvalidArgumentException
     *   MUST be thrown.
     *
     * @return array|Traversable
     *   A traversable collection of Cache Items keyed by the cache keys of
     *   each item. A Cache item will be returned for each key, even if that
     *   key is not found. However, if no keys are specified then an empty
     *   traversable MUST be returned instead.
     */
    public function getItems(array $keys = array());

    /**
     * Confirms if the cache contains specified cache item.
     *
     * Note: This method MAY avoid retrieving the cached value for performance reasons.

CacheException

This exception interface is intended for use when critical errors occur,
including but not limited to cache setup such as connecting to a cache server
or invalid credentials supplied.

Any exception thrown by an Implementing Library MUST implement this interface.

<?php

namespace PsrCache;

/**
 * Exception interface for all exceptions thrown by an Implementing Library.
 */
interface CacheException
{
}

InvalidArgumentException

<?php

namespace PsrCache;

/**
 * Exception interface for invalid cache arguments.
 *
 * Any time an invalid argument is passed into a method it must throw an
 * exception class which implements PsrCacheInvalidArgumentException.
 */
interface InvalidArgumentException extends CacheException
{
}

Since psr/cache version 2.0, the above interfaces have been updated to add argument type hints.
Since psr/cache version 3.0, the above interfaces have been updated to add return type hints. References to array|Traversable have been replaced with iterable.
