> (This is from a Y! Bugzilla ticket 1821593, adding it here. . Originally
> posted by Leif Hedstrom on 2008-03-19):
> Currently you have to set static keep-alive idle timeouts in TS, e.g.
> CONFIG proxy.config.http.keep_alive_no_activity_timeout_in INT 8
> CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 30
> even with epoll() in 1.17.x, this is difficult to configure, and put an
> appropriate timeout. The key here is that the
> settings above need to assure that you stay below the max configured number
> of connections, e.g.:
> CONFIG proxy.config.net.connections_throttle INT 75000
> I'm suggesting that we add one (or two) new configuration options, and
> appropriate TS code support, to instead of
> specifying timeouts, we specify connection limits for idle KA connections.
> For example:
> CONFIG proxy.config.http.keep_alive_max_idle_connections_in INT 50000
> CONFIG proxy.config.http_keep_alive_max_idle_connections_out INT 5000
> (one still has to be careful to leave head-room for active connections here,
> in the example above, 20000 connections
> could be active, which is a lot of traffic).
> These would override the idle timeouts, so one could use the max_idle
> connections for incoming (client) connections,
> and the idle timeouts for outgoing (origin) connections for instance.
> The benefit here is that it makes configuration not only easier, but also a
> lot safer for many applications.
