From b10b34a8f204ed409a6fc936e199557bfe3b0975 Mon Sep 17 00:00:00 2001 From: Fred Hebert Date: Tue, 14 Jan 2014 13:30:58 -0500 Subject: Support ad-hoc keep-alive for HTTP/1.0 Clients Only go for keep-alive if they submit a 'connection: keep-alive' header in the request, keep behaviour the same otherwise. The new RFC 7230 (http://tools.ietf.org/html/rfc7230#section-6.3) states: If the received protocol is HTTP/1.0, the "keep-alive" connection option is present, the recipient is not a proxy, and the recipient wishes to honor the HTTP/1.0 "keep-alive" mechanism, the connection will persist after the current response; Even though clients are discouraged from doing so in Appendix A.1.2 (http://tools.ietf.org/html/rfc7230#appendix-A.1.2) --- test/http_SUITE.erl | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'test') diff --git a/test/http_SUITE.erl b/test/http_SUITE.erl index e5a9256..0417ad0 100644 --- a/test/http_SUITE.erl +++ b/test/http_SUITE.erl @@ -426,6 +426,34 @@ http10_hostless(Config) -> [{port, Port10}|Config]), cowboy:stop_listener(http10_hostless). +http10_keepalive_default(Config) -> + Normal = "GET / HTTP/1.0\r\nhost: localhost\r\n\r\n", + Client = raw_open(Config), + ok = raw_send(Client, Normal), + case catch raw_recv_head(Client) of + {'EXIT', _} -> error(closed); + _ -> ok + end, + ok = raw_send(Client, Normal), + case catch raw_recv_head(Client) of + {'EXIT', _} -> closed; + _ -> error(not_closed) + end. + +http10_keepalive_forced(Config) -> + Keepalive = "GET / HTTP/1.0\r\nhost: localhost\r\nConnection: keep-alive\r\n\r\n", + Client = raw_open(Config), + ok = raw_send(Client, Keepalive), + case catch raw_recv_head(Client) of + {'EXIT', _} -> error(closed); + _ -> ok + end, + ok = raw_send(Client, Keepalive), + case catch raw_recv_head(Client) of + {'EXIT', Err} -> error({closed, Err}); + _ -> ok + end. + keepalive_max(Config) -> {ConnPid, MRef} = gun_monitor_open(Config), Refs = [gun:get(ConnPid, "/", [{<<"connection">>, <<"keep-alive">>}]) -- cgit v1.2.3
