== HTTP Status Codes ==


The following is original research, and thus should not be used directly to edit the article, but it may lead to someone finding a citation to a reliable source that confirms it.

The article says:

"''<nowiki>Soft 404s can occur as a result of configuration errors when using certain HTTP server software, for example with the Apache software, when an Error Document 404 (specified in a .htaccess file) is specified as an absolute path (e.g. http://example.com/error.html) rather than a relative path (/error.html).</nowiki>''"

I just tested this on Apache 2.2.20, and found that when I put " ErrorDocument 404 http:/www.example.com/ " in the .htaccess file, it serves up the file with a 302 redirect status code, not a 200. (" ErrorDocument 404 / " serves up the document with a 404 status code. ) --[[User:Guy Macon|Guy Macon]] ([[User talk:Guy Macon|talk]]) 19:47, 20 November 2011 (UTC)

"Google Chrome includes similar functionality, where the 404 is replaced with alternative suggestions generated by Google algorithms, if the page is under 512 bytes in size."

That bug was fixed in Feb 2011: http://code.google.com/p/chromium/issues/detail?id=36558

== Missing historical information ==

This Article is missing the information on where the name 404 historically comes from. Please ad it.

404 was the name of the first server room. so whenever there was a problem people had to go there.

If you are going to add anything about the above, it should be noted that that story is an urban myth and the 404 code is based on a logical system of status codes and has nothing to do with any room in CERN or anywhere else.  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/60.229.237.17|60.229.237.17]] ([[User talk:60.229.237.17|talk]]) 22:35, 15 June 2012 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

== Page name ==

If the WP protocol is to be followed, shouldn't the page name be '''404 error'''? — The redirect page "[[404 error]]" is near the top (currently #6) on the page stats list:[http://stats.grok.se/en/top] and HTTP 404 doesn't even make the top 1000 list.  ~''Regards, ~E'' : [[Special:Contributions/74.60.29.141|74.60.29.141]] ([[User talk:74.60.29.141|talk]]) 06:58, 17 March 2013 (UTC)
:You might have a good point. Currently, '''404 error''' is #59 and '''HTTP 404''' is #822. That shows that more users are using the redirect than accessing the article directly by an order of magnitude. I also get more Google Books hits for "404 error" (~6k) than for "http 404" (~2k), but even these are edged out by hits for "404 not found" (~8k).

== Github ==

[[Github]] returns fake 404 errors for pages that are hidden from the public. This can be paradoxical if someone creates a private fork of a public project and then does a pull request. The existence of the private fork, and its commit hashes, will be visible to the public, but any attempt to access it will result in 404.

When it becomes verifiable, we'll know to add it to the article.

== "optional, mandatory, or disallowed ... message" ==

At the beginning of the Overview paragraph...

"... numeric response code and an optional, mandatory, or disallowed (based upon the status code) message"

This says the message is one of (i) optional, (ii) mandatory, or (iii) disallowed.

I don't think this is what was intended.  It doesn't make sense.  This is what happens with amateur contributors and editors who don't have a good grasp of the English language.  I would have corrected it but it's not possible to discern from the sentence what was actually intended.

On a secondary point of style, the parenthetical clause should be removed from the middle of the sentence and placed at the end, following a comma and without the parentheses.

== Minimum Chrome error page size for replacement ==

According to https://bugs.chromium.org/p/chromium/issues/detail?id=36558 and https://src.chromium.org/viewvc/chrome?revision=75887&view=revision Chrome will only replace 404 pages which have 0 bytes of size (this may mean "Custom error pages" needs to be updated).

'''Identifying 404 Error Pages'''
There are several possible ways to identify 404 (Page Not Found) error pages on a website:
* '''Browser Indication:''' When you try to access a non-existent page on a website, most modern browsers will display a “404 Not Found” error message in the browser window.
* '''HTTP Status Code:''' The server responds with an HTTP status code of 404 when a requested page or resource is not found. You can check the status code in your browser’s developer tools (usually by opening the Network tab and inspecting the response headers).
* '''Server Log Files:''' Web servers typically log all incoming requests, including those that result in 404 errors. You can analyze the server log files (e.g., Apache’s access.log or Nginx’s access.log) to identify 404 errors and the requested URLs that caused them.
* '''Web Crawling/Scanning Tools:''' Various web crawling and scanning tools, such as Screaming Frog SEO Spider, can be used to crawl a website and identify 404 error pages. These tools will report the URLs that returned a 404 status code.
* '''Google Search Console:''' If you have your website registered with Google Search Console, you can check the “Crawl Errors” report, which lists the URLs on your site that returned 404 errors when crawled by Google’s bots.
* '''Site Search:''' Some websites have a built-in search functionality. Attempting to search for a non-existent page or term can sometimes trigger a 404 error page.
* '''Broken Link Checkers:''' There are online tools and browser extensions (e.g., Broken Link Checker for Chrome, Ahref Broken Link Checker) that can scan a website or specific page for broken links, which often result in 404 errors.

== Unproven information  ==

“The term "404 Not Found" was coined by the creator of HTTP Tim Berners-Lee, who explained in a 1998 interview that he wanted to make the error message "slightly apologetic". He also said that he considered using "400 Bad Request" instead, but decided that it was too vague and technical.”
