JDK-6627897 - File is not updated when downloading it via applet.
Description
The plugin caching mechanism is not checking resource files for updates upon browser reloads. resource files which are updated on the webserver end are not being conveyed in applet on client end. See comments for testcase.
Comments
EVALUATION After communication with Thomas - it seems that this is the default behaviour for the JRE 6.0 plugin. We don't recheck cached files for validity during a brower session or relaunch (init()) of an applet. Cu can use the "no-store" http cache-control directive if they wish for the plugin not to cache resource files which update frequently. Cu is looking for some document updates and clarification around cache handling though. Will handle this as a different matter.

WORK AROUND a)clearing the classsloader cache via x key in console panel b)disabling cache in control panel. c)disable caching of URLConnection via setDefaultUseCaches(false)
