Setting a custom userAgent in HTML or JavaScript

Question

Is there any way to do this? I\'m trying to send a GET request to a website, but I want to customize my UserAgent. Is there any way to do this in pure HTML and JavaScript? I

Answer 1

You can programmatically do this in Javascript (this example mocks up Firefox):

navigator.__defineGetter__('userAgent', function () {
    return "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0)"
});
navigator.__defineGetter__('appName', function () {
    return "Netscape"
});

You can then view the changes in the console via (and of course check these via Javascript):

navigator.userAgent
navigator.appName

Here's an example of a test that should work (using Jasmine):

describe("isUserAgentInternetExplorer", function () {
    it("should return false for Firefox", function () {
        navigator.__defineGetter__('userAgent', function () {
            return "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0)"
        });
        navigator.__defineGetter__('appName', function () {
            return "Netscape"
        });
        //your code here...
        expect(...your code here...).toEqual(false);
    });
});
