What’s the best way to automatically redirect someone to another webpage?

// use this to avoid redirects when a user clicks "back" in their browser
window.location.replace('http://somewhereelse.com');

// use this to redirect, a back button call will trigger the redirection again
window.location.href = "http://somewhereelse.com";

// given for completeness, essentially an alias to window.location.href
window.location = "http://somewhereelse.com";

edit: looks like the user who posted the better answer has left SO, i’ve consolidated his answers here.
