I'm on rackspace's cloud sites service, so I can't modify my server environment. I'm also running Drupal 7. I've spent the last couple days looking for a way to minify JS in Drupal 7 and it is my conclusion that one does not exist yet. Am I wrong? Or do I need to wait for a D7 release of http://drupal.org/project/advagg?
Minify module also minify HTML.
