thank you,
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 ?

Damien,
