determine the structure of the directories and files in the caches. You can clean out
the caches by simply deleting the version file.
When the server starts up, if it does not find the version files, it deletes the
directory structure for the corresponding caches and re-creates the version files.
Next time the server serves a JSP page, it recreates the JSP class cache. The next
time the server serves a JSP page or servlet while using
session manager, it recreates the session data cache.
If a future upgrade of the server uses a different format for the caches, the server
will check the number in the version file and clean up the caches if the version
number is not correct.
