How to wrap request and response to generate customized request and response using servlet filters?

Question

I want to write a filter that will be invoked before the request reaches to the servlet and want to do some modification in the request and then want to forward to the servlet.

Similarly, I want to modify the servlet generated response using the filter and want to forward the customized response to the client.

You would need to extend HttpServletRequestWrapper and HttpServletResponseWrapper and override respective methods. Please refer to below links for examples:

Hope this helps!
