Troubleshooting anti-forgery token problems

Question

I have a form post that consistently gives me an anti-forgery token error.

Here is my form:

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
         


        

Answer 1

AntiForgeryToken also checks your logged in user credentials haven't changed – these are also encrypted in the cookie. You can turn this off by setting AntiForgeryConfig.SuppressIdentityHeuristicChecks = true in the global.asax.cs file.
