 Hi,

 there's a bug on IIS7 which sets `$_SERVER['REQUEST_URI']` to "/index.php"
 instead of leaving it empty (as afaik it should be on IIS):
 [http://support.microsoft.com/?kbid=954946 KB954946]

 The value of `$_SERVER['HTTP_X_ORIGINAL_URL']` contains the right URI and
 should be used instead of `"/index.php"`.

 Usually `REQUEST_URI` is set to the value of `HTTP_X_ORIGINAL_URL` in
 `wp_settings.php`, [/browser/trunk/wp-settings.php#L67 line 67], but
 because that block is protected with a ` if ( empty(
 $_SERVER['REQUEST_URI'] ) ) ` it does not get used on our server.

 I know there's a

 -4aef-8c99-5f13862ac386 patch for KB954946] but not all wordpress users
 might be able to apply patches to their servers; is there any reason why
 we cannot use `HTTP_X_ORIGINAL_URL` right away if it is set and not empty?
