Was sending an article to a client explaining the benefits of using HTTP auth instead of the 'defacto' cookie/session based authentication.
That led me to read another article form the same guy. Check it out, shoppping cart without sessions. As the web becomes more 'mashable' and web applications become more like the default interface to a web service, the concepts he's writing about are good for any developer to use.
That's it, enough web tech ramblings for now.
