Huh? do you mean a:
Client ==>Squid ==> Parent==> Internet ??
'Sibling' is a two-way mesh term, meaning two proxies at teh same level:
Client ==> ProxyA => ...elsewhere
|||
Client ==> ProxyB => ...elsewhere
So ProxyA and ProxyB are siblings, both can re-route requests sideways if
their upstream link fails or if its faster to go that way.
What your config does at present for both proxies is:
> http_port 8080
- listen as a regular proxy on port 8080
> cache_peer proxy1 parent 8080 0 default originserver
- fetch requests by default from parent web server (originserver) proxy1
port 8080.
NP: Squid decodes the regular proxy requests and converts them into
webserver client requests (ie. "GET / HTTP/1.0" instead of "GET
http://proxy/ HTTP/1.0") when sending to originserver peers.
I'm not sure what exactly you are after, but its one of these two setups:
1) Squid proxy gateway with a parent upstream proxy gateway.
(All requests from proxy1 routed through proxy2 parent)
proxy1:
http_port 8080
cache_peer proxy2 parent 8080 0 default
prefer_direct off
proxy2:
http_port 8080
2) two sibling proxies providing failover to the internet.
(all requests go in internet until that machines external link fails,
then they go through sibling)
proxy1:
http_port 8080
cache_peer proxy2 sibling 8080 0
prefer_direct on
proxy2:
http_port 8080
cache_peer proxy1 sibling 8080 0
prefer_direct on
Hope this helps. If not please provide some exact details of what request
flow you are aiming to achieve.
