How to validate jqery ajax call asp.net
===

I have a web application where I have used http-handlers and jquery for ajax call.<br/>
Now the problem is user can type the same url in the browser which is generated by the jquey and operation is being performed.<br/>
Can I send some token with the query string and then on server side I can look for the right token before performing any operation.
<br/>Hope that I have written my problem correctly.
