[otrs] Can caching be disabled for static stats?

Hi, I'm figuring out static stats by tinkering with code in StateAction.pm. Problem is, to see any change in action I first need to run otrs.DeleteCache.pl and then restart Apache (don't know if they both are required but it's a way I found to be working so I'm sticking with it for now) OTRS's manual says caching can be disable but I haven't figured out how to do it or - important - if it can be done just for static stats. http://doc.otrs.org/3.1/en/html/stats-managing-the-stats-module-by-the-sysad... Beside wishing this for development, having caching disabled in production - just for static stats - would be highly desirable in my situation. Can anyone help with indications on how to disable caching? Thanks, Bogdan
