Re: [squid-users] can squid bypass few ips!

i'm not sure, if this works - try using a cgi, like:

#!/bin/bash

echo -e "Content-Type: application/x-ns-proxy-autoconfig\r"
echo -e "Cache-Control: no-cache\r"
echo -e "Pragma: no-cache\r"
echo -e "Expires: `date`\r"
echo -e "Date: `date`\r\n\r"

echo 'function FindProxyForURL(url, host) {
    if (isPlainHostName(host)) {
        return "DIRECT";
    } else {
        return "PROXY 194.49.70.45:3128";
    }
}'

so you can say, that this file must not be cached.
