Sure. I do not doubt that
Let's assume we have a Domain www.mycomain.com
that belongs to customer X.
Customer X has no experience with .htaccess or mod rewrite.
He wants to set up subdomains that redirect like this:
sub1.mydomain.com -> www.mydomain.com/main.php?action=sub1
sub2.mydomain.com -> www.mydomain.com/bla.php
sub3.mydomain.com -> www.mydomain.com/thatsme.html
I know that you can do all this via httpd directives or .htaccess but that's sort of a problem for customers that can only use the ispc interface, isn't it?
I could change the ispc code of that installation myself, but I didn't yet understand if there's a reason that you can only redirect co domains to directories in ispc.
