Hi, I am having problems with mod_rewrite using the following; Options +FollowSymlinks RewriteEngine On RewriteBase / RewriteRule ^dir/([\d+]+)$ /re_engine/script.php?var1=$1 The above should match this www.domain.com/dir/test or this www.domain.com/dir/test_underscore but I end up with a 404 and no messages in the logs. TIA Simon
