The session is pretty much the only place you've got to keep information between pages. In the above example, in step 1, you need to save the current location in session. You can do that in f() before you return, or if you want to always do it (from every c/f), you could perhaps do it in your layout.html: copy the location from request to session. (That won't work for redirects, but you might not want it to.)
