[Seaside] Accessing and changing the url - adding and reading variables

[sergio ruiz]

In my current app, the user enters a zip code and and distance to retrieve
concert dates.

Once the user enters that data, and has results, I would like to make it
very easy for the user to share this link with their friends, or save the
link for later use.

How would I go about rewriting the url on the way out, and reading that
data on the way in?

thanks!
