How to make a redirect with the required UserAgent using Javascript?

Question

JavaScript

Good day. There was such a task. When the user goes to the page, I need to change his user agent and redirect to a specific page so that exactly the user agent that I specified is visible on this page. Is it possible to do this with Javascript? I have doubts about the fact that this is even possible, but maybe someone will tell you for sure =)
Well, if it is not possible, then maybe someone will tell you by means of which this can be done. Thanks in advance for your reply.
PS Here on this site (do not take it for advertising) you can do something similar. You can write your user agent and the address of the page to which you need to go with this user agent.

Answer 1

No way. Proxy through your server.

Answer 3

navigator.__defineGetter__('userAgent', function(){
    return 'МОЙ СУПЕР БРАУЗЕР';
});
