watt.cachedirective.
watt.cachedirective.exclude.packages
Specifies a comma-separated list of packages whose Dynamic Server Pages you want the browser to cache. You can specify the packages as regular expressions. The asterisk (*) is the only wildcard character allowed in the regular expression. By default, the value of this parameter is empty, meaning none of the Dynamic Server Pages in the Integration Server Administrator are cached.
Note:Software AG recommends that you use watt.cachedirective.exclude.packages to cache the Dynamic Server Pages that are related to custom packages only.
Important:
If you change the setting of this parameter, you must restart Integration Server for the changes to take effect.
