 Hi,

 I've a special case with a site using wordpress site only for specific
 part of it.

 At the root of my site, I have the following /.htaccess file:
 {{{
 RewriteEngine On
 RewriteBase /

 RewriteRule ^bar/(.*)$ foo/bar/$1 [L]
 }}}

 The idea is that I want to emulate[[BR]]
 /bar/[[BR]]
 /foo/[[BR]]
 [[BR]]
 Where /foo/ is the main wordpress MU installation, and /foo/bar/ is an
 additionnal site. Now the problem: if I access /bar/, I'll have the /foo/
 site showing up, and tell me the bar article is not found.

 The problem is that Wordpress only look out for REQUEST_URI, and never for
 REDIRECT_URL.

 I can't figure out where is the exact route handler in wordpress, so I've
 not been able to make a full-fix yet, but for now, I think a part of the
 problem might reside in wp-includes/classes.php, WP::parse_request(), on
 line ~159:
 {{{
 $req_uri = $_SERVER['REQUEST_URI'];
 $req_uri_array = explode('?', $req_uri);
 $req_uri = $req_uri_array[0];
 }}}

 My fix suggestion would be to replace the previous code by the following:
 {{{
 $req_uri = $_SERVER['REQUEST_URI'];
 $req_uri_array = explode('?', $req_uri);
 $req_uri = isset($_SERVER['REDIRECT_URL']) ? $_SERVER['REDIRECT_URL'] :
 $req_uri_array[0];
 }}}

 But I still have the same problem, so I didn't put the fix at the good
 place. I've made a search and the REQUEST_URI variable is used in 33
 files. So if the parse_request is not the route parser...


 ... how can we make WordPress (MU) support parent Url Rewriting ?
