The Native HTTP Support does not support HTTP Keep-Alive. It's easy to test with uwsgi --http-socket :8080 and using telnet to send a valid HTTP/1.1 request; uwsgi will close the socket after sending the response.

A well-behaved HTTP/1.1 server will keep the socket open unless the client requests Connection: Close.

Excellent, thanks! I see it now. On another note, if anybody has any recommendations for another server to check out that has proper http keep-alive support, I'd be glad to hear it.
