Switch firefox to use a different DNS than what is in the windows.host file

Question

For example, I have a development site on a different server but I\'m trying to copy content over from the live site so it\'d be handy to have the live site in IE and the dev si

Answer 1

Since http proxy protocol is similar to raw http protocol, you can redirect desired traffic to your development server by telling firefox it's a proxy server.

two limitations:

A. this won't let you use https connections.

B. some frameworks (e,g: wordpress) don't like this method and redirect the request the wrong way

just copy the following code into a .pac file (enter your site domain and IP address, of course), and switch development/production just by changing proxy configuration.

function FindProxyForURL(url, host) {
    var prox4site = {
        "mysite.com":"PROXY 10.0.1.100:80",
        "www.mysite.com":"PROXY 10.0.1.100:80"
    }

    return prox4site[host] || "DIRECT";
}
