Great tutorial. This was exactly what I was looking for, now I have a question, how would you apply this set up to a multi-site set-up? I have the following directories in my sites folder, example.com, example2.com, etc. How would I set the settings.php in each directory, or how do I adjust the .htaccess to be able to hide the "main" dir and have a multi-site setup? I was successful in setting up a multi-site but after applying the methods in this tutorial, I have lost multi-site access. Any help and input is much appreciated. Thank you.
