To decrease the number of connections for connection manager dynamically.
-------------------------------------------------------------------------

                 Key: HTTPCLIENT-894
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-894
             Project: HttpComponents HttpClient
          Issue Type: Question
          Components: HttpClient
    Affects Versions: 3.1 Final
         Environment: Windows
            Reporter: Alok Chaudhary
            Priority: Minor
             Fix For: 3.1.1


Hello,

I have a quick query regarding MultiThreadedHttpConnectionManager. At the application startup,
i fetched no of connections value from my cache. Based on the connection value, i initialized
MultiThreadedHttpConnectionManager.

MultiThreadedHttpConnectionManager  mgr = new MultiThreadedHttpConnectionManager() ;
mgr.getParams().setDefaultMaxConnectionsPerHost(10); 
mgr.getParams().setMaxTotalConnections(10); 
HttpClient client = new HttpClient(mgr) ;

Now if i dynamically increase the no of connections say "12" in my cache then my netstas shows
me 12 connections. I dont have any issue in this.
But when i dynamically decrease the number of connections say "8", connection manager does
not reflect the "8" connections. Netstat still shows "12" connections in established state.

I have 20 threads those are using my HttpClient, so i dont want to shut down my connection
manager.

My questions are:
 1) Is there any way or alternative to decrease the connections dynamically without shutting
down connection manager?

  2) What will happen to those threads using my client if i shutdown my manager in bertween
request processing?

Any help will be appreciated.
