No dice.

Tried setting it globally first and for fun at the VirtualHost level, 
too, with the same results,   :8080   in any of our URLs when the 
trailing / is omitted.

As much as I hate to say it, this is a show-stopper for me right now 
with getting Varnish in play in our environment.

Anyone have any other ideas?

Many thanks,
Kevin
