Re: back functionality
Technically the referrer header is an optional part of the http spec, so cannot always be relied upon (though most browsers do behave, you may get issues with odd proxies misbehaving). The only really reliable way to do this is to tag the previous page in your session (best in a beforeFilter / afterRender) and use that. But yeah, for the majority of circumstances Chris's method would work fine.

Re: back functionality
store the previous page in a session and use that to make the link, or use the javascript history object.
