Tuning URL invocation cache
The URL invocation cache holds information
for mapping request URLs to servlet resources. This cache is Web container-based,
and shared for all Web container threads. A cache of the requested
size is created for each Web container thread that is available to
process a request. The default size of the invocation cache is 500.
If more than 500 unique URLs are actively being used (each JavaServer
Page is a unique URL), you should increase the size of the invocation
cache.
