Hi all,

I am using ajax for some request but when the user session expire, I get  
a ActionController::InvalidAuthenticityToke error.

Do you know how I could trap this error and redirect to the login panel  
?

I tried to put a begin … rescue … end over the code, but it doesn’t  
work.

Is someone have an idea about this problem. I will have to disable  
forgery if there is no solution …
