I need to read this spec!

I don't think any used browsers support this yet.

This sounds cool.  Just read the spec.  I'm not sure how you can (on
successful login) _redirect_ the user to the orginal stored URL with
request parameters intact.  I'm guessing that it will always stay the same
URL.  I don't think I solved redirecting browsers from request's stuffed
with POST data, and keeping them.  I guess the servlet container could
always play tricks (storing the data in the server, and feeding them into
the request on success).  Cannot wait to see the code for this.

I'm still struggling with how to merge these authentication systems with
the simple authorization schemes they tend to insist upon (ie: user can or
cannot do, based on the name or their group).

Well, anyway, thanks for the update!
