I have a quite simple need : to redirect any request to a single file.

So I put, at my apache directory root, a .htaccess :

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^ index.php?q=test [L,QSA]
</IfModule>

All the requests are indeed redirected to index.php but a wierd thing appears : the PHP $_SERVER['QUERY_STRING'] contains q=test&q=test showing that the redirection occurs twice (and the REDIRECT_URL doesn't contains index.php but the passed URL leading to it being equal to REQUEST_URI.

How can I fix that, considering that I have only .htaccess way to configure Apache ?

Testing :

• Create a folder at your apache web root (ex: redirect/)
• add a .htaccess file containing the code above
• add a index.php file dumping $_SERVER to see the result
• try any URL (ex: redirect/foo/bar) and you should see the dump.

Apache version : 2.4.33 ; PHP version : 7.2.4 (& 5.6.35) ; WAMP (Win) & Red Hat (Linux).
