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.

 Connection of the svc_handler with the remote host. This method also encapsulates the connection done with auto_purging under the hood. If the connect failed due to the process running out of file descriptors then, auto_purging of some connections are done from the CONNECTION_CACHE. This frees the descriptors which get used in the connect process and hence the connect operation can succeed.  |
