//Which is the better way? Perform FS read during response.write or independently?
//Read during response write
response.write(function() {
	fs.readFile('./index.html', function (error, html) {
		if (error) {
			throw error;
		} else {
			return html;
		}
	});
});
//Read then write response
fs.readFile('./index.html', function (error, html) {
	if (error) {
		throw error;
	} else {
	    	response.write(html);
	}
});
