Fun with Node.js Pipes

pipes.js

// Include required modules.
var http = require('http');

// Globally available vars.
var endpoint = 'search.yahoo.com';
var proxyPath = '/search?p=';

// HTTP server for client requests.
var server = http.createServer(function (clientRequest, clientResponse) {

	clientRequest.setEncoding('utf8');

	// Get the inbound HTTP request.
	clientRequest.on('end', function() {


		// Extract the search term from the request URL (ugly, but it works).
		var searchTerm = clientRequest.url.substring(1, clientRequest.url.length);

		// Create HTTP client to send request to endpoint.
		var options = { host: endpoint, port: 80, path: proxyPath + searchTerm, method: 'GET' };
		var request = http.request(options, function(proxyResponse) {
		      // Pipe the HTTP client response from endpoint back to the HTTP server response.	
                      proxyResponse.pipe(clientResponse); 
		}).end();

	});

}).listen(3000);

Start the proxy server:
~$ node pipes.js
