Hmmm. Perhaps it would be better to make an acl like...

acl myHost dst 10.10.10.10

...and then instead of "http_access allow all" use "http_access allow
myHost". Maybe using vhost and vport doesn't open you to abuse when you
have a cache_peer with the originserver directive, but it sure makes me
nervous...

Laughable, considering you have a 100 MB cache partition. :o)

I see you have further information in another email...
