ACE 6.0.5

A connection strategy which caches connections to peers (represented by SVC_HANDLER instances), thereby allowing subsequent re-use of unused, but available, connections. This strategy should be used when the cache is bounded by maximum size. More...

A connection strategy which caches connections to peers (represented by SVC_HANDLER instances), thereby allowing subsequent re-use of unused, but available, connections. This strategy should be used when the cache is bounded by maximum size.
Bounded_Cached_Connect_Strategy is intended to be used as a plug-in connection strategy for ACE_Strategy_Connector. It's added value is re-use of established connections and tweaking the role of the cache as per the caching strategy. Thanks to Edan Ayal <edana@bandwiz.com> for contributing this class and Susan Liebeskind <shl@janis.gtri.gatech.edu> for brainstorming about it.
