Substituted the above for the "insert"  Thanks.

That is what I was afraid of. ;)

That is what I thought so it must be something in my apache vhost  
configuration.  It really doesn't make sense yet, to me.

At least I now know that it does or should work.  That is the  
important thing for me for now.

If I can get it going, the doc's that exist are pretty good.  I think  
that a solid varnish is more important that the doc's for now.

Thanks for all your help and your work on varnish.
