Hey, For anyone interested I have solved this one. Instead of using SetEnv I am doing a catch all match after enabling the rewrite engine in each vhost: RewriteEngine On RewriteRule ^(.*)$ $1 [E=SISTER_SITE:foo.a.com] Then in the conf file for the rewrites i do the matches as: RewriteCond %{REQUEST_FILENAME} ^/bar$ RewriteCond %{ENV:SISTER_SITE} (.*) RewriteRule ^.*$ http://%1/bar [R=permanent,L] On Mon, 2007-04-23 at 11:13 +1000, Nikolai Lusan wrote: > Example: > > Site "Sister" Site > www.a.com foo.a.com > www.b.com foo.b.com > > in VirtaulHost for www.a.com > > SetEnv SISTER_SITE foo.a.com > Include common_rewrites.conf > > in VirtaulHost for www.b.com > > SetEnv SISTER_SITE foo.b.com > Include common_rewrites.conf > > Then in common_rewrites.conf > > RewriteCond %{REQUEST_FILENAME} ^/bar$ > RewriteRule ^.*$ http://%{ENV:SISTER_SITE}/bar [R=permanent,L] > > > This approach does not seem to work, although the environment variables > can be used in the RewriteCond statement they seem to be ignored in the > RewriteRule statement. -- Nikolai Lusan Systems Administrator Hitwise Pty.
