---------------------------------------

             Summary: [perf] cache url and request path for default Resource implementations
                 Key: MYFACES-3778
                 URL: https://issues.apache.org/jira/browse/MYFACES-3778
             Project: MyFaces Core
          Issue Type: Improvement
          Components: JSR-344
            Reporter: Leonardo Uribe
            Assignee: Leonardo Uribe


Checking performance of the latest 2.2.x code, I have found that both url and request path
for default Resource instances are calculated over and over, but they never change. The reason
is you cannot add resources to the path dynamically, which means all resources are static
and does not change over application lifetime, so it is safe to store these two values in
the cache and reuse them. 

The only side effect detected is if two mappings (prefix and suffix) are used on the same
application, the request path for a resource will not be according to the current mapping,
but that's ok because one or the other should just the same.

This will improve performance a bit. The reason is before this patch, each Resource instace
requires calculate the url and the request path. This is relevant for composite components,
because each composite component requires create 1 Resource instance each time it is instantiated.
