    httpdispatcher is a simple class allows developer to have a clear dispatcher for dynamic pages and static resources. Classes http.ServerRequest and http.ServerResponse earns new params property containing a map of received HTTP parameters. Using httpdispatcher is pretty simple:

        var HttpDispatcher = require('../httpdispatcher');
        var http           = require('http');
        var dispatcher     = new HttpDispatcher();
     
        dispatcher.setStatic('/resources');
        dispatcher.setStaticDirname('static');
     
        dispatcher.onGet("/page1", function(req, res) {
            res.writeHead(200, {'Content-Type': 'text/plain'});
            res.end('Page One');
        }); 
     
        dispatcher.onPost("/page2", function(req, res) {
            res.writeHead(200, {'Content-Type': 'text/plain'});
            res.end('Page Two');
        });
     
        dispatcher.beforeFilter(/\//, function(req, res, chain) { //any url
            console.log("Before filter");
            chain.next(req, res, chain);
        });
     
        dispatcher.afterFilter(/\//, function(req, res, chain) { //any url
            console.log("After filter");
            chain.next(req, res, chain);
        });
     
        dispatcher.onError(function(req, res) {
            res.writeHead(404);
            res.end();
        });
     
        http.createServer(function (req, res) {
            dispatcher.dispatch(req, res);
        }).listen(1337, '127.0.0.1');
        
        
        /*
        GET  /page1  => 'Page One'
        POST /page2  => 'Page Two'
        GET  /page3  => 404
        GET  /resources/images-that-exists.png => Image resource
