Hi,
I tried trunk and I don't get any blank page with it. I'm sorry I
didn't try it earlier.

That's the point, I just needed a quick way to purge an URL.
Later I'll definetely purge it from the backend.

Thanks for your reply, I'm still learning a lot about Varnish,
especially the difference between pass and pipe. Actually the "pipe"
for POST and req.http.Expect were taken from the default vcl.
If I understand correctly "pipe" means that further data between
client and server is passed until the connection is closed, while
"pass" means that the current request will be passed, but further
requests in the same connection will be normally processed by the vcl
file (and could be looked-up, for example).
Is this correct? Would you please make some examples where "pass" and
"pipe" are preferred?

Thanks,
Marco
