G'day,
Just wondering if anyone here has had any experience with daisy-chaining
squid proxy servers. In particular I am interested to know if the following
scenario is possible:
User-->ProxyA-->ProxyB1-->..->ProxyBn-->ServerA
|
---->ProxyC1-->..->ProxyCn-->ServerB
1. User specifies a proxy server (ProxyA) in his browser.
2. Request from proxyA is then redirected to either ProxyB1 or ProxyC1
depending on the name of the destination servers (host names, not domain
names).
Is it possible to use url_regex in squid.conf to redirect the user to
another proxy server? For instance, given the following url_regex, how would
I redirect acl 'subnetA' to use ProxyB1 and vice versa?
acl subnetA url_regex ^http://server1*
acl subnetB url_regex ^http://server2*
Auto-proxying is quite easy to do using javascript (e.g. proxy.pac) - by
simply skipping ProxyA and going directly to either ProxyB1 or ProxyC1.
However, this requires me to constantly update the acls on both proxies when
new users are added, which can be a real pain.
Please feel free to share your ideas.
Thanks,
SH
