Searching on the forums and Google hasn't turned up much information, so I hope someone can help shed some light on the subject for me.

I am trying to avoid having to restart the Apache server every time a user adds or deletes a domain or pointer, so I have turned to mod_rewrite. However, I do not see a way to give unique values to each website for mod_throttle or suexec (User and Group).

I did note that someone mentioned they use several files to map the suexec User to a domain, but I don't see how they could do that and they did not elaborate.

.htaccess could possibly be an option, but I have read about severe performance problems with this option as .htaccess files multiple.

What have other admins used for this problem?

Thanks in advance!
