Subject RE: HTTP Cache Manager attributes
Date Wed, 29 Oct 2014 13:08:15 GMT

Thanks very much for the clarification.

Is there anything to monitor to see if items are getting ejected from cache by the LRU algorithm?

The HTTP Cache Manager is used to add caching functionality to HTTP requests within its scope
to simulate browser cache feature.
Each Virtual User thread has its own Cache. By default, Cache Manager will store up to 5000
items in cache per Virtual User thread, using LRU algorithm.
Use property "maxSize" to modify this value. Note that the more you increase this value the
more HTTP Cache Manager will consume memory, so be sure to adapt -Xmx option accordingly.
