>1. Why are you using such an old build of 6.0.x? 2. You cannot set headers when any part of the response has already been sent to client. At that time headers have already been sent over the wire. See ServletResponse.isCommitted(). 3. You should be careful with that header. If you set it to a wrong value you may break something. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
