I have two sites. One is a subdomain site and the other is a subdirectory site.
I have some users who started their sites as a subdomain but now want to have a subdirectory while keeping the subdomain name. This is not an issue using standard apache virtual hosting for example where I can simply have a virtualhost then in it's html directory, put a small index.php file which redirects the user to http://www.mydomain.com/users-new-blog.
Since I have a catch all DNS for the subdomain site, is there a directory where I could put my index.php file for example, in order to redirect users to the subdirectory site?
