How to create a chrome extension that redirects to a particular link automatically?

Question

Hi I want to create a chrome extension so that when the user is on the page example1.com he would automatically be redirected to example2.com even before the page loads. this should work whether or not the user types in the url or goes there through a link.

Please help me in this!

Thanks.

In background page:

chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
    if(tab.url.indexOf("http://example1.com") == 0 && changeInfo.status == "loading") {
        chrome.tabs.update(tabId, {url: "http://example2.com"});
    }
});
