I thought it was because there's a lot about http that's overhead and/or tough to get right, which can then be delegated to the server.

Also, websockets actually map pretty badly to http, conceptually, and fit zeromq much better IMO.

Regarding websockets (admittedly off-topic re Mongrel though), I recently found out about Pushpin[0], which seems to be an elegant way to translate WS into HTTP, should it be of interest to someone. Basically a proxy-server that takes care of accepting either websockets or HTTP on the front, and talking only HTTP on the other side.

I evaluated PushPin for a project recently but ended up going with Nchan

Pushpin uses Mongrel2 under the hood to handle incoming WebSocket connections, so not entirely off topic. :)

It's pulled in as a dependency and launched in the background.

I thought PushPin was based on Qt?

[jkarneges]

It's multi-process. The core logic is a Qt application, but it delegates the external protocol I/O to separate processes. Mongrel2 handles inbound and Zurl handles outbound (Zurl is a project of ours that is basically the inverse of Mongrel2).

[wink]

Parts of mongrel2 were sadly a solution in search of a problem. Mostly the "let's redo FastCGI via ZMQ". Was still immensely fun working on and with it.
