How to force disconnection in commons-httpclient ?

Question

Hi,

I use commons-httpclient to send queries to a Web server. The Web server never closes connections, but has a small memory leak associated to the connection context.

I would therefore like to close the persistent connections from time to time (every X queries for example), but I did not find any way to do this. I use the MultiThreadedHTTPConnectionManager

I could use MultiThreadedHTTPConnectionManager.closeIdleConnections(very_small_delay), but that's not very reliable: if my Java code has much work to do, then it's possible that no connection is ever idle, because there are always other threads waiting for a free connection.

Thanks,

Answer 1

Are you calling method.releaseConnection()?

Answer 2

after executing one method, let's say GET, you can read the responsed HttpStatus number, to decide if a method.releaseConnection() needs to be called.

Or if you know which connection you wanna close, you could try

MultiThreadedHTTPConnectionManager
void    releaseConnection(HttpConnection conn) 

okay, I thought you have some reason that you want to 'kill' a connection. Assume you have the connection, the HttpConnection Object, which you want to close in hand. May this method help?

HttpConnection
public void close()

    Closes the socket and streams.
