strange is it.
varnishncsa generates lines with ip= 127.0.0.1, i suppose
this represents the requests to the backends ?
I think it could be interresting to arrange varnishncsa to add
at least two fields that would be
1) if the request was a cache or misss
2) the duration of the delivering
it would ease the debugging
is that planned sometimes ?
