Easy way to simulate Invalid Viewstate?

Question

Is there an easy way to simulate Invalid Viewstate?

Answer 1

Sure: just add a simple javascript function to the page to modify the hidden __VIEWSTATE input.

Answer 2

You can also use fiddler

It can simulate a postback very easily and you can modify that post.

Answer 3

Here's a jQuery way to implement Joel's suggestion:

<script language="javascript">
$(document).ready(function() {
    jQuery('input[@name=__VIEWSTATE]').val("this is now bad");
});
