I'm not sure how many people are running varnish with the origin server available on a flaky WAN connection. There might be issues.

Waiting list?
We've got a varnish server that we're trying to put into production, but it seems to get itself into a very bad state after only an hour or so of being up. All requests end up like this: 92 SessionOpen c 64.81.61.44 46900 92 ReqStart c 64.81.61.44 46900 1629712861 92 RxRequestc GET 92 RxURLc / 92 RxProtocol c HTTP/1.1 92 RxHeader c User-Agent: curl/7.16.3 (powerpc-apple-darwin9.0) libcurl/7.16.3 OpenSSL/0.9.7l zlib/1.2.3 92 RxHeader c Host: go24.cn 92 RxHeader c Accept: */* 92 VCL_call c recv 92 VCL_return c lookup 92 VCL_call c hash 92 VCL_return c hash 92 Debugc "on waiting list on obj 1629712739" 0 StatAddr 64.81.61.44 0 nan 16 16 0 0 3 5483 637585 That's it. After the "waiting list" message the request just hangs indefinitely. The only noteworthy piece of information I can think of is that the connection between the varnish server and the back end is slow and prone to packet loss. (Varnish is in China, backend is in the USA.) ___ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc

If the other session gets a cacheable response, this session will return that cached reply, but if the result is not cacheable, this session will then have to go to the backend. The idea here, is that when an object is not in the cache, we should not send hordes of clients to the backend after it, if the first one can do the job alone. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | 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
Debug: On Waiting list?
Hi,
Im struggling with a couple of high response times when using
varnish on our site. I have configured varnish so it will
cache only static content (jpg,gif,png,css,js etc) even if a
cookie is set. But all our jpeg's are getting a high response
time when Im running some test against the site.
One of the jpeg's are pic_mini.jpg, it has a response time of 357ms. I turned
on logging and vcl_trace and found the line:
14 Debugc "Hash Match:
/Portals/0/Picture/pic_mini.jpg#www3.mydomain.com#"
14 Debug c "on waiting list on obj 1767384108"
Does "on waiting list" has something to do with the high response time?
The rest fo the log for pic_mini.jpg is:

In vcl_recv im fetching static content using:
sub vcl_recv {
# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
lookup;
}
# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
lookup;
}
if (req.http.Cookie) {
# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
lookup;
}
# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
lookup;
}
}
pass;
} #RECV
and my vcl_fetch is using:
sub vcl_fetch {
# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
insert;
}
# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
insert;
}
if (obj.http.Set-Cookie) {
# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
insert;
}
# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
insert;
}
pass;
}
#
pass;
} #FETCH
