Added HttpServerSettings.keepAliveTimeout.
c9e8e6b 
Fixed the return value of Libevent2TcpConnection.waitForData.
The HTTP server checks for client disconnects before reading a consecutive request of a keep-alive connection now (avoids "operating on closed connection" errors).
Fixes issues #20 and possibly #43.

Can you recheck if this still occurs? From the log output I think it is fixed with the previous commit.

This was happening for me in a snapshot from 28ba2df, but appears fixed in 6230af0.

Was very reproducible: just wait 10-15 seconds after loading a page, and the exception comes up. Then the next page load will hang. Very annoying, very good to be gone.

Ok thanks, I'll close the issue then for now.

Turns out this is still happening. Easy to reproduce in Chrome with pipelining enabled or Firefox with pipelining enabled.

It was happening less but I still get it all the time.

Changed the way how active disconnects are done for libevent based TC…

Turned out that TcpConnection.close() was not working correctly. It's somehow rediculous how difficult such things can be to get right with libevent-like libraries compared to bare metal socket code - caused by hidden state that they introduce and which is not really documented.
