Re: What if Squid goes down?

Here's one for you...Make up something to return this:

Content-Type: application/x-ns-proxy-autoconfig

function FindProxyForURL(url, host)
{
    return "PROXY proxy.vianet.on.ca:3128; DIRECT";
}

This script will tell both Netscape and MSIE (the newer ones, anyway) to
contact 'proxy.vianet.on.ca:3128' for all requests, and to run direct to the
target site if it cannot be contacted for some reason. If the connect fails,
and the browser starts connecting directly, it will try periodically to
obtain a successful connection to the proxy server, and return to using it.

You can list multiples, as well. I have a second box set up with a minimal
cache (a measly 10MB) in case the first one is down or in maintenance (since
drawing from our provider's proxy is half the byte-cost of going direct)..So:

return "PROXY proxy1.domain.com:3128; proxy2.domain.com:3128;
proxy.afriendofours.com:8080; DIRECT";

is also possible. You can list about as many as you like, but MSIE will hate
you after four or five.
