Alan M. Carroll commented on TS-518:
------------------------------------
Is it presumed the origin server has sent a FIN or RST on the connection?
> Close UA connection early if the origin sent Connection close:, there's a bad
> Content-Length header, and the UA connection has Keep-Alive.

>
> In a very special case, we could improve the user experience by forcefully
> closing the connection early. The case is
> 1) The origin server sends a Content-Length: header that is wrong, where the
> CL: value exceeds the actually body size.
> 2) The origin server either sends a Connection: close, or it uses HTTP/1.0
> without keep-alive.
> 3) The client (and TS) uses Keep-Alive to the UA.
> In this case, we can end up stalling the UA until either the UA or the TS
> connection times out. It might make sense to prematurely disconnect the
> client when this case is detected.
