Hi Liam

Are you sure about that? HttpClientBuilder will use maxIdleTime value for both expired and
idle connection eviction and will default to 10 seconds if not explicitly set.

Connection eviction policy - you explain how to clean-up connections. Although I can argue
against the design as without this if server closes connections, my client gets many sockets
stuck on CLOSE_WAIT - adding this thread solves the CLOSE_WAIT issue. 
> However, I don't understand why you don't do this yourself if keep-alive is set. I would
expect the library to support such a thread. In the meanwhile, it seems that if I use the
default connection manager, I can't use non-deprecated code to call :
> connMgr.closeExpiredConnections();
> and
> connMgr.closeIdleConnections(30, TimeUnit.SECONDS);
> This is because the only exposed API to get the default pooling connection manager is
by calling:
> httpClient.getConnectionManager(), which is deprecated. Javadoc suggests to go to the
builder (which I do use but not for creating connection pool as the default is good enough
for me) which is useless.
> So - how should one acquire a reference to the connection manager?
