My university provides a public_html file in each student's Linux directory so tat each student can have a webpage. I want to put all my PHP scripts into that file and place the index in a sub-directory called webroot. I'm trying to work out a way to have an .htaccess file in the public_html that will redirect ALL requests in that folder to be redirected.

There's lots of advice on redirecting any file that doesn't exists but I want to redirect regardless of the existence of a file. Can I use something like RewriteCond TRUE?
