Varnish, Plone and Apache2
I have one site running Plone with lighttpd and Varnish that I set up as documented here: http://bitubique.com/content/accelerate-plone-varnish I have now been asked to set up others substituting Apache2 for lighttpd by the developers, but haven't been able to find such detailed instructions for Apache2. I believe I just need to find the Apache equivalent for this line from lighttpd.conf: proxy.server = ( /VirtualHostBase/ = ( ( host = 127.0.0.1 , port = 6081 ) ) ) To my understanding something has to listen on port 80, send the request to Varnish, which then either serves from the cache or sends the request on to the Zope (Plone) port. If anyone knows offhand or has some experience with this I'd like to hear from you. Is Apache a bad choice for this? -- Charles Farinella Appropriate Solutions, Inc.

still trying to purge
Hi all,
For the moment I have given up trying to do the http purge thing and am
trying to find a workaround. I have the following shell script:
==
#!/bin/sh
host=127.0.0.1
port=6082
cmd=url.purge
param=.*
echo open ${host} ${port}
sleep 1
echo ${cmd} ${param}
sleep 3
echo exit
==
The result of this script is:
==
./clearcache.sh | telnet
telnet Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
105 20
Too many parameters
Connection closed by foreign host.
==
If I put any other command in the script, it works fine. If I
use 'url.purge' as the command, but '^/$' as the parameter, that works
fine. Only the '*' or '.*' throws the 'too many parameters' error.
What is the correct command and format to purge the entire cache?
If anyone has a solution for me I would be very appreciative. If I
cannot find an automated way for the web development people to clear
this cache at will, I'm going to have to try to set up Apache or Squid
to do the caching and I'd just rather not do that. :-)

You need something in your vcl_recv as well, to match against the
purge acl, and force it to lookup on an acl match. It would go
nicely inside the pipe if not GET or HEAD request from the default
vcl like this:
sub vcl_recv {
# [...]
if (req.request != GET req.request != HEAD) {
if (req.request == PURGE) {
if (!client.ip ~ purge) {
error 405 Not allowed.;
}
lookup;
}
set req.http.connection = close;
pipe;
}
# [...]
}
My error, we have this section in our vcl file, I forgot to include it.
Perhaps we just misunderstand what should be happening. What exactly
will the command 'PURGE /' remove from the cache? We are trying to
empty it.
We need to have web developers have the ability to clear the Varnish
cache. Currently we are doing it for them by telneting to the Varnish
management interface and running 'url.purge *'. We'd like to protect
them (and us) from that if possible.
I got several responses, thanks to all, but no joy so far.

http purge help
I am new to Varnish, am trying to implement HTTP purging, and
getting 'not found' responses. If anyone has a moment to look over
our configuration and make some suggestions or point out errors,
we would be grateful, we are at our wits end.
We have Varnish running behind lighttpd on port 6081 proxying
a Plone installation, so we have lighttpd at port 80, Varnish
at port 6081, and Zope/Plone at port 8080. All are working as
expected.
uname -n = nec.appropriatesolutions.com
We have our vcl.conf configured like this:
###
acl purge {
localhost;
127.0.0.1;
}
sub vcl_fetch {
# force minimum ttl of 300 seconds
if (obj.ttl 300s) {
set obj.ttl = 300s;
}
}
sub vcl_hit {
if (req.request == PURGE) {
set obj.ttl = 0s;
error 200 Purged;
}
}
sub vcl_miss {
if (req.request == PURGE) {
error 404 What you have requested is not in cache;
}
}
###
We are attempting to send the purge request with a Python script, like
so:
###
#!/usr/local/bin/python
from httplib import HTTP, HTTPConnection, HTTPResponse
h = HTTPConnection('127.0.0.1:6081')
h.request('PURGE', '/', '', {'Host': 'www.nec.edu'})
resp = h.getresponse()
print resp.read()
status = resp.status
reason = resp.reason
headers = resp.getheaders()
print 'status: ', status
print 'reason: ', reason
print
print headers
print
###
Our varnish log is showing:
###
127.0.0.1 - - [18/Feb/2008:16:14:12 -0500] PURGE http://www.nec.edu/
HTTP/1.1 404 451 - -
and the output of the script is:
