/*
|
||||
* Cookie based authentication
|
||||
* taken from http://en.wikipedia.org/wiki/HTTP_cookie#Authentication
|
||||
*
|
||||
* 1. The user inserts his or her username and password in the text fields
|
||||
* of a login page and sends them to the server;
|
||||
* 2. The server receives the username and password and checks them; if
|
||||
* correct, it sends back a page confirming that login has been successful
|
||||
* together with a cookie containing a random session ID that coincides with
|
||||
* a session stored in a database. This cookie is usually made valid for
|
||||
* only the current browser session, however it may also be set to expire at
|
||||
* a future date. The random session ID is then provided on future visits
|
||||
* and provides a way for the server to uniquely identify the browser and
|
||||
* confirm that the browser already has an authenticated user.
|
||||
* 3. Every time the user requests a page from the server, the browser
|
||||
* automatically sends the cookie back to the server; the server compares
|
||||
* the cookie with the stored ones; if a match is found, the server knows
|
||||
* which user has requested that page.

embeddable web server.

This application was written for educational purposes demonstrating

how web interface could be decoupled from the business logic. Not a

single line of HTML is generated by the server, instead, server

communicates data in JSON format using AJAX calls. Such chat server

could be used in your application as a collaboration tool.
