Hi All

How can I put configuration with parent proxy servers?
I have 2 ISP. One has proxy address other one has not proxy address(I can use with no proxy from client browser).

How can I do for these 2 ISP?

Thanks

I have not played with squid for some time, but I used to do heaps with it...
From your message, I understand that you want to use 2 ISP at the same time via squid.

The best way, is to add a route to the linux system for the ISP with a proxy, so it knows the route to the proxy server, but use the no-proxy ISP as your default gateway.
Add rules so that certain domains go via the parent proxy, and others go direct (using the no-proxy isp, because that is the default gateway). This, i believe is part of the parent rule, and is documented.
From when I was dealing with squid on a regular basis, there was no way of configuring direct and parent proxy load ballancing other then via top level or sub-level domains....
A good mix is to put .com via the parent proxy, and others direct, and mixing more into the mix as required.

Hope this helps

I don't understand this can you give me explanation for this? i have one resource you can check it.if this is useful.

Hopefully you understand the routing part, but it is basically:
route add 10.1.1.30 gw 192.168.1.1
route add default gw 192.168.1.2
where 10.1.1.30 is the ip of the proxy server, 192.168.1.1 is the router to the proxy isp and 192.168.1.2 is the router to the no-proxy isp

It would be easier if both ISPs have a proxy, as this would make configuration much easier such as:

Howerver if they don't (you should ask them to check - because they might, and not advertise it), you will need to define some acl rules on which way to go:

cache_peer 10.1.1.30 parent 3128 0 name=isp1proxy default
cache_peer_access isp1proxy allow all

acl directdomains dstdomain .com
never_direct deny directdomains
never_direct allow all

replacing 10.1.1.30 with the ip address of the parent proxy, and 3128 with the port of the parent proxy

Hope this helps...
