Ah, I see!  Hmmm.

Well in that case, is there any reason why I shouldn't simply do
something like:

  varnishlog -c -o RxHeader "Host: (www\.)?example1\.com" >
/path/to/logs/example1.log &

  varnishlog -c -o RxHeader "Host: (www\.)?example2\.com" >
/path/to/logs/example2.log &

...etc for each site, logging each to a separate varnish log file?

I could then use varnishncsa's '-r' option to convert them into NCSA
format once the logs are rotated out.  It seems like that would do
pretty much what I want.

Many thanks,
Marcus
