OK... What is the "CPING / CPONG For Dummies" version? :-) I found http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html which doesn't really help me... it presupposes that I know an awful lot more than I do. Is there a walkthrough somewhere that tells me how I'd go about CPINGing and CPONGing that starts with the assumption that I have no idea what they are? :-) -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * *********************************************************************** --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
