Is there a way to reload a website rather than get the 400: Bad Request message? I think that the error is being thrown by the decorator function @http.route, because I have auth='public'. And I need it public, so please no auth='none' answers. 

On my website is a form with an input field and submit button. I want that when user clicks submit and if the session expires it redirects him to the same site before the POST submit.

Can this be done?
