I have 2 filters in my application. Based on some condition, I want to choose whether to execute the second filter or not. Is there a way to do this?

I did some googling with no success. I want the request to continue without executing the second filter. Is that possible?

Any help will be appreciated.

In addition to Colin's answer, there's another way: just don't call FilterChain#doFilter(), but RequestDispatcher#forward().

if (condition) {
    request.getRequestDispatcher(((HttpServletRequest) request).getServletPath()).forward(request, response);
} else {
    chain.doFilter(request, response);
}

But this will skip all filters from current on, expect of the ones which are listening on <dispatcher>FORWARD</dispatcher>.
