Just use prepareRequestFunction and watch for TCP connections (in Linux for example)

I suppose that the reason is that timeout event from the socket is not handled, so the connection wouldn't be closed, as in case of timeout it should be closed manually.

PS: i guess that my issue couldn’t be the same as for the topic starter, but might be related as well. My issue is related to the active connections that are managed by the library growing despite actual connections with proxies closed and the browser that initiated the connection is closed as well, so the library doesn't recognize some cases of the closed connection.

Hello guys, thanks for your effort to report this issue. We have released version 2.2.1 that should not leak TCP connections anymore.
