[xwiki-users] redirecting upon login

Hi all, I've a kind of an urgency so, please, accept my apologies if I didn't browse lists and issues looking for a similar doubt. I am in a meeting where I will use XWiki to present some ideas about collaboration driven with a wiki-wiki environment (and XWiki will be presented as the BEST option to create such an environment!). I do need to do a simple thing: I have a document with two versions. One of them can be freely accessed (this is the case http://tinyurl.com/4lc34s) and the second one that is now freely accessible (http://tinyurl.com/6qxhnw) but access must been restricted. Of course I can control this access with users' rights, but how could I forced logged users to go to the second release and not logged users to the first one? The perfect situation would be that active links in http://tinyurl.com/6qxhnw will be only showed when logged (or logged with an granted access user). Any idea will be welcome! Thanks for your help!
