I'm trying to set up squid as a web accelerator behind apache for a
couple of slow dynamic sites I have.
Well, first trouble is that accelerators should be in _front_ of the web
server. Apache has perfectly fine caching internally for cachable
content. All the benefit from acceleration comes from taking the load
off before it gets near Apache.
I have lots of virtual hosts in
Apache and I want to be able to proxy a couple of them through squid.
In Apache I have this for one of my virtual hosts:
RewriteRule ^/(.*)$
http://127.0.0.1:3128/http://212.100.249.204:7171/$1 [L,P]
However, when I try to access the address I get this error:
"Access Denied. Access control configuration prevents your request
from being allowed at this time."
I'm using webmin, and I can't figure out what rules I need to setup in
order to allow the request. I've even tried having an Allow All rule,
but that didn't make any difference.
If anyone can give me some pointers I'd be extremely grateful.
Slow:
client -> Apache
Attempt 1:
client -> Apache -> Squid -> Apache
now guess how much work Apace is now doing?
better to try this:
client -> Squid2.6 -> Apache
apache config - same as before, just serve on a non-80 port (single
machine setup) or point DNS at the squid server (multi machine setup)
(use a recent 2.6 for accelerating)
squid: (assuming apache is on 1.2.3.4 port 81
http_port 80 vhost defaultsite=www.example.com
# www.example.com for broken clients who try to
# GET without saying which domain.
cache_peer 1.2.3.4 81 0 no-query no-digest no-netdb-exchange
originserver name=web
# if you can list the domains accelerated easily
# you may also want an ACL pre-filtering the domains
acl accelSites srcdomain www.example.com
cache_peer_access allow accelSites
http_access allow accelSites
