[users@httpd] Filters in Apache?

[Anthony Smith]

I know that if I was doing this in java I would need a filter, but if my sites under apache just includes pictures and html docs, with some cgi, I am unsure if a filter is really what I need.     I was trying to figure out a way, where based on the URL path  could do certain things.   If someone goes to:   http:/mysite.com/alpha -> This would maybe check the header information for a certain variable (anything under the alpha directory (files or folders)) http:/mysite.com/beta -> This would forward you to beta.mysite.com (anything under the beta directory (files or folders)) http:/mysite.com/gamma -> This would maybe check the time of day and if it is after 5pm forwards you to a static page that says it is after 5pm.   Is anything like this possible?
