What do you mean by Trash ?

Is there an errors in the Log ?

I didn't mean trash ,but shopping cart. The buyer selects the product, adds it to the shopping cart ,and when entering it, throws it on the login form(username and password).

Form to login is shown even if he is logged?
That is for a specific user or all users?
Have you checked the system log?

Are you using a farm (multiple servers)?  Maybe you need to use a MachineKey setting in your web.config
