I need to provide my site the feature of logged-in users, i.e.I would like to use hidden form fields storing some sort of identifier so to recognize a remote user after he has first logged in. Do not do that. It is very tedious.

This is because you need a form to have a hidden form field. All your internal links must then be wrapped by a form. Following the link becomes a form submit. You end up with lots of Javascript (which many persons disable due to security concerns).

This to avoid using the default HTTP authentication, which sends username and password in the clear for every request. I know CMF does this using cookies, does anybody know any tools/products/anything using hidden form fields for this purpose? There is a product that allows session ids to be coded as part of the URL. This way, you can avoid cookies. I do not know its name.
