Passing Data Between Views without saving it to cookies

[eluser]Doulos[/eluser]
I'm working on a project that has a series of pages and on each page displays the data from the previous pages in a side bar.

The data I'm dealing with isn't data I want to put into a cookie and may, in some cases, be too large to do so anyway. But I also Want to hit the controller to check authentication and do some different redirecting depending on the type of user between each page.

So my question is how do I move the data between pages(each page has a controller function and several possible views)? Can I pass data to a controller so I could pass it back down to a view? If so, What's the syntax for the link from each page to the next to make the controller accept data?

Thanks!
