How can I replace Apache HTTP code 404 to 200

Question

I don't want the apache of a website return any HTTP code 404,
the reason is that the accreditation council will scan all the website,
many javascript links and some incidents will cause the 404 code,
in fact, those links are valid but that checker will misjudge error.
So, i want to prevent the apache to return HTTP code 404,
How can I configure apache return HTTP cods 200 instead of 404 and show my define error page?

Answer 1

I use this:

<?php header("Status: 200 OK"); ?>

This code has to be put at the top of the .php file in the first line of code. Search engines, crawlers, browsers and anyone accessing the site will see the errordocument 404 page as a header 200.

Header 200 means the page exists. Google will crawl and index sites with header status 200.

From: http://www.askapache.com/htaccess/apache-status-code-headers-errordocument.html

1. Create a blank file in your main web directory named 404.. can be blank.

2. Add this to your .htaccess file:

   Redirect 200 /404
   ErrorDocument 404 /404
   

That will change the Apache ErrorDocument to the /404 file. But the Redirect line causes requests for /404 to issue a 200 OK response instead of a 404.

If that doesn't work it is due to rewrites no doubt. So if that's the case add this under those first 2 lines but above any other rewrite lines in your .htaccess file:

Options FollowSymLinks ExecCGI

RewriteEngine On
RewriteBase /

# If the requested file doesnt exist
# and if the requested file is not an existing directory
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^[^4]* /404 [L,S=4000]

i think you can use this below simply code into PHP:

header("HTTP/1.1 200 OK");

you can test it.
