keep-alive or not keep-alive
Solution 1:
Why not to set keepalive timeout to, say, 15 seconds? I don't see a reason to keep every connection for 2 minutes. And I don't think the browser will keep the connection for 2 mins according to this link: http://en.wikipedia.org/wiki/HTTP_persistent_connection#Use_in_web_browsers, 1 minute timeout seems to be more realistic.
