Hi Per,<br><br>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.<br>
<br>Another question - is there an easy way to monitor the average pageload time that varnish experiences when contacting the backends?<br><br>Many thanks for your help,<br><br>Alex<br><br>--<br><br><span style="font-family: courier new,monospace;">backend wwxx {</span><br style="font-family: courier new,monospace;">
