Ajax Question

A way to avoid many servlets

I want to avoid having many servlets because it doesn't seem right that for each button or resource on the page there will be a special servlet for it.

What I aim for is to make different ajax requests to the same servlet, and in that servlet to be able to differentiate between them in the


For example:

function bar() {
url: "servletName",
success: function(data) {

function baz() {
url: "servletName",
success: function(otherdata) {

What can I add to the request to be able to differentiate between them (with if elses or switch)?

PS: I also have an html5 request (I think) so I would like to add something to it as well to make it distinct:

$(document).ready(function () {
$("#uploadbutton").click(function () {
var formData = new FormData();
formData.append("myfile", document.getElementById("file").files[0]);
var xhr = new XMLHttpRequest();
xhr.open("POST", "rooms", false);
document.getElementById("status").innerHTML = xhr.responseText;


The so obvious thing you have to do is, passing an extra parameter in get and post requests from your AJAX requests and checking the parameter inside servlet using request.getParameter("type"); // type is what you are sending from client to detect the ajax request.
