HTTP Authentication

[wookayin]

HTTP Basic Auth would work out, but standard HTTP authentication is not supported on Safari and WebSockets.

So, we can do the following:

• Add HTTP authentication on the HTML page, and set a Cookie (varies per session)
• Websocket packet includes the cookie, which is validated by the server app

In order to this we need to maintain an in-memory authentication information and mapping of user-cookie pairs.
