Very Cool.  If you ever make it production quality (and can port it to
3.0 when it comes out) I would love to integrate this into the release.

You'll want to handle things like:
    Last-Modified:
    Expires:
    Content-Length:

TimBL: According to the spec data formats are per RFC850, so they are like:
    Last-modified: Tuesday, 05-Oct-93 22:58:33 GMT
I'm not sure that's the right RFC to standardize on.  Wouldn't 822 make
more sense?
