I should add: For what I gather are performance reasons, Varnish does
not have database lookup support or external map support.  You will
probably want to generate your vcl file programmatically using a map
that contains the mapped url as the key and the backend url as the
value (or vice versa).   Varnish can switch among VCL files at runtime
using the admin console.
