Direct URLs to specific caches

Hi

I habe to parent caches A 'proxyA.somewhere.com' and B
'proxyB.somewhere_else.com'. I want to direct all request for the URL
'www.gothere.com' to parent cache A. All other request shall go to both
A and B. I tried

acl direct_to_proxyA dst www.gothere.com
cache_peer_access proxyA.somewhere.com allow direct_to_proxyA

This causes squid to direct _only_ request for 'www.gothere.com' to
Proxy A. What to change to have all request distributed to A and B,
except the ones for 'www.gothere.com' which shall uniquely go to Proxy
A?

Thanks
-Thomas
