Here's what I'm trying to do.
I have a generic link that allows clients to login to my site. www.site.com/clients, I'd like to be able to have the client, depending on the login, go to the directory associated with that client using Apache authentication (popup login window)
In other words, if Acme is the company logging in, I want to append the username variable to the URL, www.site.com/clients?user=Acme so it pops up the authentication window and allows Acme to login in to their directory.
The directory name will coincide with the user name. (i.e. directoryname=username)
Can someone tell me where to start researching this so I can play around with it and get it working on my site?
I'm not looking for code, I want to do it myself, just need a direction to go and what "terms" I need to learn.
