[opencms-dev] caching of jsp can lead to great confusion

[Christian Steinert]

Hi Chris,

in the cache administration tool of opencms there is a function called "purge JSP cache".
This should get rid of any temporary JSPs in the filesystem and force the JSPs to be re-written into the filesystem in their current state upon next execution.
