I personally am really against any kind of Javascript in links, as it
messes with my browsers ability to open links in new tabs/windows on
my command.

If you want to implement solution #2, attaching a referring URL to
each and every link, you could extend/overload the HtmlHelper with
something custom that'll transparently attach the referrer to each link.
Still not very elegant with regards to pretty URLs though.
You might want to look into storing a users "browsing history" in the
Session. Since you're essentially trying to remember something for the
user, the Session would be a good place to store that information.
