And when you change file, change query string value
File reference using a query string in the URL referencing the application version, such that when the application is upgraded
(and the version is incremented), the browser will be instructed to always load the new file and ignore any previously cached files.
Or does the version attribute resolve that issue also?
Changing query string forces browser to download file again, because browser thinks it is different file as URL changes.
Ahh, I misread as #APEX_VERSION# (as seen in page templates), hence upgrading APEX env between version, as opposed to the application version property. Good to know.
