CERN Room 404[edit]

I heard, that this number came from the room number the computer was in who gave out that message. I don't know if it's true. Please check that Columbus240 (talk) 18:15, 29 January 2014 (UTC)

page views[edit]

on, how does this always manage to be the 2nd most viewed article? (talk) 11:17, 3 June 2011 (UTC)

Because (I think) so many people get in touch (on so many pages) with a 404 and they don't know what this is! mabdul 11:54, 3 June 2011 (UTC)

404 WMD in "popular culture"?[edit]

In Weapons of mass destruction in popular culture article under the The invasion of Iraq in search of Sadam Hussein's alleged WMDs section, there's a reference to the "404 These Weapons of Mass Destruction cannot be displayed" parody by ... I think it should be included / referenced here too. It was quite popular at it's moment, and a precursor of adapting HTTP-humor to current events. — Preceding unsigned comment added by (talk) 12:35, 22 July 2011 (UTC)

Yeah, that's funny. Do you have any newspaper article about it? We need a third party (independent) reference for that. mabdul 14:47, 10 August 2011 (UTC)

HTTP Status Codes[edit]

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:

"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. rather than a relative path (/error.html)."

I just tested this on Apache 2.2.20, and found that when I put " ErrorDocument 404 http:/ " 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. ) --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:

Perhaps email mmenke (see bug) if you need further information. — Preceding unsigned comment added by (talk) 19:55, 2 February 2012 (UTC)

Missing historical information[edit]

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. — Preceding unsigned comment added by (talk) 11:13, 9 June 2012 (UTC)

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. — Preceding unsigned comment added by (talk) 22:35, 15 June 2012 (UTC)

How does User: know about this origin? Is there a source for this? BeenAroundAWhile (talk) 15:57, 4 May 2015 (UTC)

Page name[edit]

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:[1] and HTTP 404 doesn't even make the top 1000 list. ~Regards, ~E : (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). Does anyone have any other thoughts on the most appropriate title for this article? Wilhelm Meis (☎ Diskuss | ✍ Beiträge) 04:02, 9 November 2013 (UTC)
We might also look into HTTP 403, which I would suggest moving to 403 Forbidden. Wilhelm Meis (☎ Diskuss | ✍ Beiträge) 04:15, 9 November 2013 (UTC)


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. Meneth (talk) 13:12, 30 May 2013 (UTC)

It's not a particularly notable subject, and sounds more like a (possibly deliberate) mistake in the way the system handles erroneous requests. If memory serves, the correct error would be a 401.  drewmunn  talk  13:42, 30 May 2013 (UTC)

"optional, mandatory, or disallowed ... message"[edit]

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.

Anybody can edit. Also anybody can sign messages with four fildes (~). BeenAroundAWhile (talk) 15:59, 4 May 2015 (UTC)

Slang section?[edit]

I feel that the slang section does not belong as a subsection of the IIS section. Lythronaxargestes (talk) 19:16, 19 August 2016 (UTC)

Minimum Chrome error page size for replacement[edit]

According to and Chrome will only replace 404 pages which have 0 bytes of size (this may mean "Custom error pages" needs to be updated). (talk) 10:51, 9 January 2017 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on HTTP 404. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
