You send heartbeats! There might be a max-connection-time but I haven't run into it, my connections being dropped through amazon infrastructure was solved by sending a few bytes (': <3' or '<!-- <3 -->') every 5 seconds or so.

TCP keepalive should solve the problem too. Rather than HTTP keepalive.

(i.e. To handle the case of "HTTP-Request", "huge delay", "final response". Rather than a streaming/chunking reply that is very long/slow.)

See my sibling post. TCP keep-alive can work, but you probably need to fiddle with OS-default settings for modern network equipment. I personally find the behaviour abhorrent, but my beard has more grey in it every day and I've accept that "this is how it is now"
