Custom error page 400,401,403,404 etc?

Question

PHP

I make a redirect, I registered in .htaccess

ErrorDocument 400 http://mysite.ru/error.php?error=400
ErrorDocument 401 http://mysite.ru/error.php?error=401
ErrorDocument 403 http://mysite.ru/error.php?error=403
ErrorDocument 404 http://mysite.ru/error.php?error=404
ErrorDocument 500 http://mysite.ru/error.php?error=500
ErrorDocument 503 http://mysite.ru/error.php?error=503

In error.php I'm already processing and displaying the corresponding message
. Does the server return error codes or do I need to set them?
How are search engines reacting to this?

switch($_GET['error']) {
    case 404:
        header("HTTP/1.1 404 Not Found");
        break;
} //и т.д

Answer 1

Open firebug and look at the response headers.

Answer 2

Apache will first give the redirect header
httpd.apache.org/docs/2.2/mod/core.html#errordocument
and then you need to give yours in the code

Answer 3

50x errors will not be handled in a mess! 503 for example, nginx returns when the puff daemon is turned off (or has fallen). In this case, how can the handler process the code if it is turned off?

Answer 4

IMHO is better without GET, for example,
and there is a separate view under it or whatever you have
