I had a similar issue at one point but if I remember correctly I just had to have my webserver send the header section without closing the connection.
Usually things would just get streamed through but for some reason until the full header was sent the proxy didn't forward and didn't acknowledge the connection.
Not saying that is your issue but definitely was mine.
