URL redirect:

1. Enter url in browser
2. Browser sends request to web server
3. Web server responds back to the browser with the new url
4. Browser sends a new request to the new url
5. Webserver directs the request to handler and sends back response to the browser

URL rewrite:

1. Enter url in browser
2. Browser sends request to web server
3. Web server re-writes the url and passes it to the handler and sends back response to the browser

The browser is designed to handle both of the above.

However, when I make a url request via javascript (or jquery) located on the html page, then how does the api call handle redirect response from the server?
