Modifying Servlet Filters Request/ Response

Extending custom HttpRequest class with HttpServletRequestWrapper serves many purposes:

• Modiying request body.
• Modiying request headers.
• Modiying response body.
• Modiying response codes.
• Convert GET to POST/PUT or vice-versa.

public class CustomHttpRequest extends HttpServletRequestWrapper{

// TODO

// Code goes here

// Methods implemented here

}

public class CustomHttpResponse extends HttpServletResponseWrapper{

// TODO

// Code goes here

// Methods implemented here

}
