Add the following to the application

All requests that you want to intercept must go through it. As you can see, it takes the original method requestand overrides the method getRequestURL(), returning a different value. You still have access to the original request if you want to create a new URL on the old one.

In the end, you should continue processing the request chain.doFilter(), but by providing a wrapped request, not the original one.
