Hi,
Here's what I'm trying to do: I'm building a web-based cueing system for a theatre. Until I figure out how to use WebSockets, my system will use JavaScript to refresh the webpage every second with a "cue status file". This is an HTML file built on the fly by VB (or Python). One second latency is no problem. The problem: Unfortunately (for this application) Tomcat caches the web page internally for 5 seconds by default, so the maximum cumulative latency is 6 seconds which is a bit much. I believe I can change this by setting the CacheTTL parameter but, when I try to do this in BASEDIR/conf/context.xml by adding the line <cacheTTL=1000>, the server won't start and spews out many lines of error messages. I am a total newcomer to Tomcat but I've spend some hours trying to find examples of config files on the web with little success. Obviously I haven't understood the syntax required here so any help is gratefully received. Environment: Tomcat 8.0.12 Windows 7 / 32bit Robert
