<<|[[PmWiki.Variables]]|>> :$EnableDiag:(:include AvailableActions#BEGENABLEDIAG#ENDENABLEDIAG:) :$EnableIMSCaching:A variable which, when set equal to 1, recognizes the "If-Modified-Since" header coming from browsers and allows browsers to use locally cached pages. Disabled by default to help the administrator customize its page without needing permanent reloading. :$EnableStopWatch:This activates an internal stopwatch that shows how long it takes to render a page. (If you have a wiki that composes a HTML page from multiple pages, such as a normal layout with a sidebar, you'll get separate timings for each subpage and for the total page.) : :The timings can be displayed by adding [@@] in the wiki template. : :Valid values are: $EnableStopWatch = 0; # No timings (the default). No HTML will be generated. $EnableStopWatch = 1; # Wall-clock timings only. $EnableStopWatch = 2; # Wall-clock and CPU usage timings. Won't work on Windows.
