Sorry if this has been asked before; I tried to find if there were searchable archives for this list, but couldn't find anything. I want to do a rewrite based on the value of a cookie. I have a rule in doc root for the domain, which directs it to the demo directory based on the third-level domain: RewriteCond %{HTTP_HOST} ^demo.example.com$ RewriteCond %{REQUEST_URI} !^/demo/ RewriteRule (.*) /demo/$1 This works fine. From there, I want to re-direct to a sub-directory with the same name as the value of the cookie phn_demo, if the cookie is set. I tried this: RewriteCond %{HTTP_COOKIE} phn_demo=(.*) RewriteRule (.*) /demo/%1/$1 but get a 500 error, which strangely doesn't show up in the logs. If the cookie is not set, I don't get an error. -- Alan Little Holotech Enterprises --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
