Support WebSockets if available #320

Closed cburschka closed 8 years ago

I totally missed these interesting things.

  1. WebSockets (RFC-6455) is a thing.
  2. Most major browsers support it now
  3. Strophe supports it

Why aren't we using it? Because BOSH is hard-coded into cadence right now. If config.xmpp.boshURL were supplemented with config.xmpp.wssURL, we could use both - even falling back to BOSH if WSS throws an exception.

Also we (specifically CalRef) couldn't use it before ejabberd implemented it this year.

Also, we still can't use it, because we're on 2.1.10, and Debian will probably update it in 10-20 years or something.

It's surprisingly easy to support on the client end, though - setting config.xmpp.boshURL to something like ws://.../ is enough.

Full support requires renaming config.xmpp.boshURL to something generic like config.xmpp.url, doing the same in ./configure, and maybe adding a shortcut flag (like "--websocket,-w") that will automatically default the URL to "wss?://server:528[01]/websocket" instead of "https?://server:528[01]/http-bind/".

The default without a --websocket flag should remain BOSH for the foreseeable future because support is still pretty dinky.
