Use pass, not pipe.

Re: varnish bottleneck?
That is correct. If you use pipe, the TCP connection turns into a straight pipe where bytes are moved from client to server, without further inspection, until either side closes the TCP connection. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. ___ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc
Re: varnish bottleneck?
I have some problem when I understand the pipe and pass.
In the official website ,
In pipe mode, the request is passed on to the backend, and any further
data from either client or backend is passed on unaltered until either
end closes the connection.
In pass mode, the request is passed on to the backend, and the backend’s
response is passed on to the client, but is not entered into the cache.
Subsequent requests submitted over the same client connection are
handled normally.
so if in the pipe mode , one of request is POST,and i set the if POST
the pipe. in this situation , I can control only the POST request go to
pipe mode.may be some GET request will be pipe also if the GET request
after the POST. right ? because the pipe mode end by either backend or
client closes the connection . and I don't know when the connect will
close . can I understand like that ? Is it rights ?
and if I set PASS,even though the GET request after the POST, it will be
handle by normally (maybe lookup or other settings I had set for GET)
Is it right ?

Yes, this is how pipe works. You might want to read up on pass vs pipe.

varnish bottleneck?
I think there are maybe some problem about varnish .My varnish's version
is 2.0.4 .I want to cache a website for everything .so I set the rules
like that
if (req.http.host ~www.abc.cn){
lookup;
}
it's well. Varnish can cache everything .but some function of the
website is unable .eg POST. So I put the POST judge before the HOST
.like that :

pipe;
}

lookup;
}
there are some problem .many of url's record can't be find in the
varnishlog .and there are no marked by the varnish eg X-Cache: MISS in
the Response Headers .
I had post this problem in this maillist .it's nothing about pipe or
pass about no marked. And there urls will go to the backend server every
time. I think is there the varnish bottleneck? whether varnish judge the
POST first ,it can't handle all .so there are some miss handle ,and go
though to the backend ? or maybe some options ,I didn't have the right
configure in the vcl ?
