Sirs:
I'm seeing some interesting behavior w/r/t HEAD requests that I'd
appreciate some insights on. Some background:
We use a foundry serveriron GT for load balancing. Its IP is
192.168.10.254.
The varnish test server is 192.168.10.101 under fedora 7, compiled
from source.
The current back-end server is nyp-web-1.corp.razz.com, at
192.168.10.80.
The foundry makes health checks to varnish every 5 seconds via HEAD
requests using HTTP/1.0.
For some reason (unless I'm interpreting this wrong), varnish is
deciding that the backend of these HEAD requests should be itself,
and the timestamp on the lookup is off by several hours:
(from varnishncsa)
192.168.10.254 - - [12/Sep/2007:18:32:28 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:33 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:38 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.101 - - [13/Sep/2007:01:32:43 -0700] "GET http://nyp-
web-1.corp.razz.com/mixer/playerdefault.swf HTTP/1.1" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:43 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:48 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:53 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
The GET request is varnish connecting to itself to check the asset
when the ttl expires. This request should instead be hitting the
backend server.
Current config:
backend default {
set backend.host = "nyp-web-1.corp.razz.com";
set backend.port = "80";
}
sub vcl_recv {
set req.backend = default;
set req.http.host = "nyp-web-1.corp.razz.com";
// block redirect loops
if (req.url ~ "^/static/static/") {
error 404 "Not found.";
}
// change all /static/ requests into / backend requests
if (req.url ~ "^/static/") {
set req.url = regsub(req.url, "^/static/", "/");
}
// strip query parameters from all swf requests (so they cache
as a single object)
if (req.url ~ "\.swf\?.*") {
set req.url = regsub(req.url, "\.swf\?.*", ".swf");
}
// force lookup on any of the static object types
if (req.url ~ "\.(swf|gif|jpg|png|js|bmp|pdf|css|mp3|xml|flv)
(\?.*)?$") {
lookup;
}
// deny any other kind of request
error 404 "Not found.";
}
Here's the output of varnishlog for the HEAD requests surrounding the
GET:

I'm seeing some interesting behavior w/r/t HEAD requests that I'd
appreciate some insights on. Some background:
We use a foundry serveriron GT for load balancing. Its IP is
192.168.10.254.
The varnish test server is 192.168.10.101 under fedora 7, compiled
from source.
The current back-end server is nyp-web-1.corp.razz.com, at
192.168.10.80.
The foundry makes health checks to varnish every 5 seconds via HEAD
requests using HTTP/1.0.
For some reason (unless I'm interpreting this wrong), varnish is
deciding that the backend of these HEAD requests should be itself,
and the timestamp on the lookup is off by several hours:
(from varnishncsa)
192.168.10.254 - - [12/Sep/2007:18:32:28 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:33 -0700] "HEAD /static/mixer/
playerdefault.swf HTTP/1.0" 200 61986 "-" "-"
192.168.10.254 - - [12/Sep/2007:18:32:38 -0700] "HEAD /static/mixer/

192.168.10.101 - - [13/Sep/2007:01:32:43 -0700] "GET http://nyp-

192.168.10.254 - - [12/Sep/2007:18:32:43 -0700] "HEAD /static/mixer/

192.168.10.254 - - [12/Sep/2007:18:32:48 -0700] "HEAD /static/mixer/

The GET request is varnish connecting to itself to check the asset
when the ttl expires. This request should instead be hitting the
backend server.
Current config:
backend default {
set backend.host = "nyp-web-1.corp.razz.com";
set backend.port = "80";
}
sub vcl_recv {
set req.backend = default;
set req.http.host = "nyp-web-1.corp.razz.com";
// block redirect loops
if (req.url ~ "^/static/static/") {
error 404 "Not found.";
}
// change all /static/ requests into / backend requests
if (req.url ~ "^/static/") {
set req.url = regsub(req.url, "^/static/", "/");
}
// strip query parameters from all swf requests (so they cache
as a single object)
if (req.url ~ "\.swf\?.*") {
set req.url = regsub(req.url, "\.swf\?.*", ".swf");
}
// force lookup on any of the static object types
if (req.url ~ "\.(swf|gif|jpg|png|js|bmp|pdf|css|mp3|xml|flv)
(\?.*)?$") {
lookup;
}
// deny any other kind of request
error 404 "Not found.";
}
Here's the output of varnishlog for the HEAD requests surrounding the
GET:
