varnishncsa and virtual hosts

[Raymond Hall]

A pretty simple hack to varnishncsa did the trick nicely:

diff -ru varnish-2.0.tp2/bin/varnishncsa/varnishncsa.c

                 * normalized the request URL.

This makes varnishncsa to log the host header separately, just after
the date sting. That way you can tell AWstats to use that field for
%virtualname

It's ugly but less uglier than the other workarounds I've seen :)
