However, it's pretty easy to set up your own filtering on content type along the following lines: * Map your filter to "/*". * Create a response wrapper that lets you get the content type from the response (see my post yesterday with example code), and/or add this ability to your own response wrapper. * In your doFilter() method, retrieve the content type and do the right thing for the right content types.
