2009/08/18 - Apache AxKit has been retired.

The following diffs to the Session taglib package enable the
internal redirect to the login page.  I've only tested them with
cookies-only sessions -- there may still be a problem with URL
sessions, but, if there is, the fix is trivial	(I just checked
for and eliminated what I think was the bug there, but, as I
said, I haven't tested it).

Although I've made some changes that should be documented in the
POD, I've not yet added the doc changes.

Also, note that the eval in _get_session_from_store was
especially frustrating as it hid errors that occurred when
directories don't exist.

In that same vein, since the module uses $SessionDir/lock for the
lock directory without documenting this, it should at least attempt to
create the directory and die if it can't.  This will probably be
included in my documentation patch.

And, Jörg, that HOWTO I promised should be forthcoming this
weekend along with the documentation updates.

Mark.
