Hi all,

I have a servlet filter that only allows
http://localhost/webapp/restricted to be access via localhost

This piece of code in the doFilter() is giving me problem

if(!req.getLocalAddr().equals("127.0.0.1")){
res.sendError(res.SC_NOT_FOUND, req.getRequestURI());
}

chain.doFilter(request, response);

java.lang.IllegalStateException: Cannot create a session after the
response has been committed

Any idea how to resolve this issue?
