Jeanremi,

There are other options 

(1) You may want to implement a custom connection manager that force-
closes connections upon release in the
HttpConnectionManager#releaseConnection method.

(2) This option is available in HttpClient 2.0 as of release 2.0.1. When
you are done using HttpClient, call the shutdown method of the
MultiThreadedHttpConnectionManager:

http://jakarta.apache.org/commons/httpclient/apidocs/org/apache/commons/httpclient/MultiThreadedHttpConnectionManager.html#shutdown()

Hope this helps

Oleg
