You are correct in saying that the URL defines the resource, and the "permanence" (I use that loosely) is quite important really. The way I translated the question was more or less along the lines of, "say I have this resource, which looks like a folder, is it going to look for an index.html file?"
Yes, that was my meaning.
As far as AJAX is concerned, that's a touchy subject with me. I try to make sure that anything I'm serving via AJAX is more-or-less personal to the person requesting it, say a message list or friends list or something, directly related to the person. There's always elegant fallbacks, and what I tend to use AJAX for (I am using AJAX as a synonym of a XMLHttpRequest object, as opposed to anything else which would be correct) is personal data related to the user currently logged in that isn't important to be indexed.
This has suggested itself to me as well -- AJAX after you're logged in, or at very least elegant fallback for the public links.
