Joomla "homepage" extension

Hello everyone, I run a website that has various "homepages" based upon what type of "group" of user you are. For example, you can go to [login to view URL] and arrive at an "All" view, or you can go to [login to view URL] or g2 or g3 to get a corresponding "G1," "G2," or "G3" view. These pages are currently hand-coded, and I would like to move it all to Joomla. The one thing that I can't accomplish with Joomla right off the bat, and for which I need help with is the following: - Based upon what address the user comes in on, or which "view" is selected I would like that to be the homepage that the user sees when they hit www.XXXX.com. So if a user enters [login to view URL], he or she will default to [login to view URL] "G1" view versus the default "All" view when he or she visits [login to view URL] the next time. We currently do this through a little PHP and cookies. So, to reiterate, I need a Joomla extension/module/whatever that will detect what page/view a user was last on/selected, and then save that information into a cookie that will be read, and then display that page when then hit [login to view URL] again. I'm sorry if that was confusing, please PM me if you have any questions. Thanks.
