modify userAgent JavaScript

Question

is it possible to modify the userAgent using JavaScript? I personally only know the getter window.navigator.userAgent, but this won't help me.

The HTTP header? No, you cannot modify the (request) headers using JavaScript. navgiator.userAgent? Only by using a trick. — Rob W

Are you using the WebBrowser control, can you use it in the Navigate method? stackoverflow.com/questions/7631740/… — gbanfill

the wp7 webbrowser control is a little bit different i think, there is no standard-solution for this. — roqstr

This should work.

navigator.__defineGetter__('userAgent', function(){
    return 'foo' // customized user agent
});

navigator.userAgent; // 'foo'

Or Object.defineProperty(navigator,'userAgent', {value:'foo'});

the last line is just the proof, isn't it? I'll try this.

Yup, just to make sure. I haven't tested in all browsers.
