You can set related values with the AddHandler directive. There are also some very powerful ENV options available with the Apache -- I'll defer to their docs, as it would be quite lengthy here. :).

In closing, I can tell you, having hacked on the actual C code for the HTTPd, that the Apache is very Perl-centric. In fact, if you're even a fair C hacker, you can pretty easily hack up a "custom" HTTPd that easily caters to your particular needs. :)
