Hi Per,
Thank-you for your help? With a minor change, your configuration worked
extremely well - is there a wiki for Varnish that I can post it? I've
written out a full, working, configuration for a two-host director below
which might be of use in the VCL examples page.
Another question - is there an easy way to monitor the average pageload time
that varnish experiences when contacting the backends?
Many thanks for your help,
Alex
