hi there, I am trying to use rails with mootools, everything just worked great. I have a little problem with the ajax thing, because every time i send a form with ajax an error occur that said something like “authentication token error”. I have read that i need to include inside the form a hidden with the authentication token, this approach fix the problem and everything worked, but i am not sure if this is secure or not? any idea Regards, Shirkavand ---
