> The exception was caught 30s after when abort() was called.
> I updated the code in DefaultClientConnection.opening(), DefaultClientConnection.shutdown() and SocketHttpClientConnection.shutdown() to call sock.shutdownInput() before sock.close(), and found the exception can be caught immediately after abort() is called.
> I'm not sure whether the fix is correct. So I submitted a issue to get help. And has the latest HttpClient package fixed this issue?
> Same issue is found in HttpPost.abort() case. My fix is let sock.shutdownOutput() called before sock.close().
> Thanks.
