In a lot of cases, however, the same technologies are used for documents. And yes, often the HTML is generated from a database. That's fine. "Document" does not equal "file on disk". The HTTP/HTML model just talks about the entities that actually hit the wire. If what you're delivering to the browser isn't a document, but rather a program running in the browser to build a document, you should be taking a deep breath and checking whether you actually need to do that.
