Documentation
Using the expiry time in the client cache, you can control how long a MIME object stays in the cache of the HTTP client - typically a Web browser. Objects that are subject to frequent change should not stay in the client cache long because the client cannot register any change to the object during this time and thus displays the old version. Objects that are seldom or never changed should have a longer expiry time in order to reduce the grid load and increase performance.
The expiry time can be specified for a folder and is then copied to all the subnodes (folders and MIME objects). To enable an expiry time that is different from the time in the higher-level folder, you can set the indicator for "individual expiry time". For such nodes (and their subnodes), the expiry time is not influenced by setting the indicator for a highter-level folder.
By choosing the pushbutton Overview Subtree in the dialog box you can display the expiry times for the subtree beneath the selected node. You may have to increase the expiry time under the subnode with Individual Expiry Time.
If the Expiry Time Active indicator is not set, implicit expiry applies, which means the client asks (provided settings are appropriate) on each access to the server whether the object is still current.
Behavior During Transport
When fodlers or MIME objects are transported, the expiry time is copied into the target system. In the case of folders, it is copied to the subnodes in the target system. For nodes without an individual expriy time, the expiry time of the higher-level folders is copied into the target system upon import into that system.
