Hi Tom,

In HttpClient 2.0 connections are never closed/deleted from a  
MultiThreadedHttpConnectionManager until it is shutdown.  Things like  
keep-alive settings and exceptions will cause connections to be closed,  
but they will still be returned to the connection manager.

HttpClient 3.0 (just about to be 3.0 beta1) adds the ability to close  
idle connections.  Have a look at the following for some more details:

<http://jakarta.apache.org/commons/httpclient/3.0/apidocs/org/apache/ 
commons/httpclient/ 
MultiThreadedHttpConnectionManager.html#closeIdleConnections(long)>

and

<http://jakarta.apache.org/commons/httpclient/3.0/apidocs/org/apache/ 
commons/httpclient/util/IdleConnectionTimeoutThread.html>
