Hi,
I assume that when you say "capture" you mean "handle" ? Or maybe wrap?
To only handle outgoing (response) data in a filter, do something like this:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws Blah {
chain.doFilter(request, response);
// Now do whatever you want with the response
// Remember though that the response is likely committed by now
}
To only wrap a response is even simpler:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws Blah {
// Do whatever
chain.doFilter(request, new MyResponseWrapper(response));
// Do whatever
}
