ok - will do.

You are correct I meant version URL.

I guess that I keep going back to the point that there may be occasions
where 'non-stable' URL's are used.  These include:

	- Reusable temporary version URL's
	- Mutability concerns

Even in a stable URL, we may even have mutability concerns as being
discussed in the current threads. You reference that the above suggestion is
not very useful, and the point is that it is not useful unless you have a
stable version URL and systems may have others.  Please understand that I
can appreciate the desire to have 'stable' version URL's from a long-lived
client cache perspective.

	Thanks,
