How to reproduce it: dial 'www.foto24.de' select the 'weiter'-link from one Product then select the yellow 'in den Warenkorb' - button in the right then select the yellow 'anmelden & bestellen' - button in the down center then select the yellow 'registrieren' - button at the rigth now fill the Form with some rubbish, password longer than 6 chars. now you will se the 'welcome new customer' page... if you now say 'view Frame-Source' it will show you the source of the Page, as if you didn't enter correct data instead of the 'welcome new User' page.

It regets the page, instead of pulling it from cache. *** This bug has been marked as a duplicate of 55583 ***
