That's not easily done, as far as I have been able to determine.
I've submitted a feature request for it..
As I understand it, you can only use hostname as part of the url when you
purge by http, but then no wildcards.
You can use full regexps when purging on the console, but then only the path
is available to match against.
I guess a workaround would be parse the log to make a list of all urls served
within the expiery limit, do your filtering on that list, and then purge all
the matching urls one by one by http.
The nsca log contains the full url including host, which i think is somewhat
unusual, so grepping for that should not be too hard.
Here is the pipe I use to get host as a separate column, that should be a
/usr/bin/varnishncsa -c -r /var/log/varnish/varnish.log | \
sed -e 's#\("\([A-Z]\+\) \(http://\([^/]*\)\)\(.*\)\)#\4 "\2 \5#g' \
