Description:
------------
I tried to find the documentation for the Documentation of HttpRequest From PECL HTTP. (I would prefer to see it in english or german)

Expected result:
----------------
I Expected to find the Documentation page, cause I am sure it existed once.
And I expected to find it via the search too.
My prefered languages are english and german.

Actual result:
--------------
Actuall Result:

The search was not able to find it.
I was searching a lot more with following links on the page an asking google...
The page was not found in my language.

After some time, I found "http://docs.php.net/manual/da/class.httprequest.php"
What is the desired documentation but in a other language.
I tried to switch the language to german, and english.
Both resulted in a 404 not found error telling the message "The manual page you are looking for (http://docs.php.net/manual/de/book.http.php) is not available on this server right now. Please check back later, or if the problem persists, contact the webmasters."

I assume that something is wrong with the Webserver Config or the database behind it, that this page can no longer be found for any language exept the langcode "da".

On the links:

https://web.archive.org/web/2016*/http://php.net/manual/de/book.http.php
https://web.archive.org/web/20160121041620/http://php.net/manual/de/book.http.php

You can see that the page was last time discovered in german language on 2016-01-21 on 04:16:20.

After that time something change that the page was delivered as 404 Error.
