How to intercept every AJAX request from a webpage

I need the way to intercept all ajax reques开发者_Go百科ts maded from page. So i need some wrapper to add my data to all users requests.

Huh... i made this work))) with help of this topic Extending an ActiveXObject in javascript i made script that intercept all ajax requests no matter what framework or browser do user use.

You can look at it here: Script

I dont think you can get this out of the box .
What you need here is a little restructuring of your client side code [ You should have already done that , but it is never too late :) ] .
Make a function that has the responsibility of interacting with server . Use this to make ALL your server requests and get data . After that whenever you need to do something at a application level ( like maybe caching data to avoid server side trip ) you can do in this function .
So something like

xhr_request( url , callback_function, params ) ;
// where xhr_request is your custom function that takes care of server interaction .

I'm looking for the same thing i think i want to modify ajax reponse on the fly i find this i'll tell you but it's hard for a script kiddies like me
