RewriteRule doesn't operate on the full URL, only on the non-host portion. You might need to do strange things w/ RewriteCond and RewriteRule instead: RewriteCond %{HTTP_HOST} ^(.*)-(.*)ezproxy.switchinc.org RewriteRule ^(.*) http://%1.%2ezproxy.switchinc.org/$1 [N] The %1 and %2 come from the captures in RewriteCond, while the $1 comes from RewriteRule. -Joe
