Jan-Michael,
If you haven't started using filters yet, that's the way to go. You make a
class that implements javax.servlet.Filter interface. This should allow you to
do what you want, but may require a different approach.

By having the configuration inside of your context in server.xml, I don't think
it's possible. I tried jocl, but couldn't get it to work with tc. Craig
McClanahan advised me to set up a context in server.xml instead to using jocl.

Maybe you can include the asp from the servlet.

I know that JSPs support including other JSPs or other static html files,
