Using My Filter for Response Header Settings

[Steve Dyke]

I am wanting to move some repetitive code into my filter.

In every doPost method of each Servlet I have:

response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );
response.setCharacterEncoding("UTF-8");

Here is a part of my Filter code to do this. I just want to know it this is the correct way:

private static class SessionAccessAwareResponse extends HttpServletResponseWrapper {
		
		public SessionAccessAwareResponse(HttpServletResponse response) {
			super(response);
			
			response.setHeader( "Pragma", "no-cache" );
			response.setHeader( "Cache-Control", "no-cache" );
			response.setDateHeader( "Expires", 0 );
			response.setCharacterEncoding("UTF-8");
			
        }
		
}

Why the response wrapper? Just use a straight-forward servlet filter.
