Recipe 1. User Login

An intranet is a very different animal than the free-ranging Internet. Whereas designers building for the Web thrive on the number of eyeballs they capture, intranet developers place a premium on their pages being seen by just the right eyeballs. Critical to an intranet is the concept of user authentication. Before anyone can browse an intranet area, he must be authenticated against the company records, and the records, of course, are maintained in a data source by system administrators.

Much—in many cases, all—of a company’s intranet is protected against unauthorized viewing. As you’ll see in this application, the term “unauthorized” means more than “not registered.” For robust authentication applications like the one you’re about to build, it means “not cleared to view this particular content,” and the content can be anything from an entire site down to an isolated area of a single page.
