RE: Url Rewriting in Tomcat4.0

[Coetmeur, Alain]

look about the Valves...

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/valve.html
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/catalina/docs/api/org/apache
/catalina/Valve.html

one limitation in using Valves
is that one cannot change the content of a request
is it has already been used by a previous valve...

this mean that probably you will have to stack
your URL rewriting valve before (over) the 
usual valves which map URL to servlets...

I've never uses valves myself but it looks like
NTKernel Device Drivers and should be very flexible.

  If you are running tomcat 4 with the apache web server then you could 
perhaps do this through mod_rewrite.  I don't think it is possible through 
Tomcat4 directly unless you want to write a servlet that responds to 
http://www.server.com/reseller by redirecting to the url you want? ;)
