Subject [5.0] [PROPOSAL] Refactored mapper
Date Thu, 15 Aug 2002 17:23:16 GMT

I have been hinting at rewriting the main Catalina mapper for Tomcat 5.

The proposal is designed to improve performance, avoid generating 
uneeded garbage String objects, and optimize the welcome files processing.

The following changes are proposed:
- Expose the decoded URI MessageBytes in the main Request interface of 
Catalina, so that the mapper doesn't have to pay the b2c cost
- Implement the new mappers as a separate set of classes in 

The new mappers will use exclusively bytes to match contexts/servlets 
and will rewrite the original URIs to handle welcome files without 
sending a redirect back to the client (in most cases).
