> The concurrent HttpClient connection manager has restrictions on how big it can grow per host and overall.  However, it does not ever evict idle connections[1].  This means that connections will remain open as long as the web server allows them, which can be hours.  That's wasteful and probably not very helpful.
> So, it would be helpful to provide two options:
> * The ability to close connection immediately after use.  This can be accomplished by sending the 'Connection: close' header with the request.  There should be an option on the HttpClientBuilder to always do this.  It would be implemented by a request filter.
> * Provide an implementation of a background sweeper thread that purges connections that have been idle for longer than a specified amount of time.
