Question about squid

[MeOrSo]

Hy you guys
I want to install squid on a server and use it only for specific sites. do you know if this is possible??
thanks for replies...

So the connection only goes through the squid proxy for specific IP's/URL's?

This might be possible, but seems like more work than it's worth.

Yep
Isn't it possible to say that in the conf-file?? i need it for the company i'm working for....

Offhand I don't remember, but the Configuration guide might be of some help.

So if this ip/url doesn't need to go through squid, what should be done? Will the request be denied, or will the connection be redirected to another server?

The Domains/Ips which are not specified should go out via gateway as usual
i'm reading through this page now....

I think it is possible in the auto config file for the browser. There you can specify like
if dnsDomainIs(host,".mydomain.example") {
return "DIRECT";
}

Ah yes, the autoproxy .pac file config file. I have a few that we toyed with using at work if it helps.

The question then becomes: is it more of a PITA to change IE proxy settings (unless you have an automated way [GPO] of doing this) on all PC's instead of doing something on the server side?

I'd look into the firewall on your OS as that might be easier. eg: Just setup some rules that look for outbound traffic to the target IP's then redirect the requests to your gateway.

i've done it now. for anyone looking for the code:

function FindProxyForURL(url, host)
{
var proxy_yes = "PROXY ProxyIP:Proxyport; DIRECT";
var proxy_no = "DIRECT";
if (shExpMatch(url, "http://www.whatever.com*")) {return proxy_yes;}
else if (shExpMatch(url, "http://en.wikipedia.org*")) {return proxy_yes;}
else if (shExpMatch(url, "http://www.anotherpage.com*")) {return proxy_yes;}
else {return proxy_no;}
}

ProxyIP ist the IP of the proxyserver or the hostname, Proxyport is the port where Squid gets the requests (default is 3128)

thank you idx
