icm/HTTP/server_cache_<xx>/ufo_expirationLocate this document in the navigation structure


This parameter sets the expiration time in seconds for the entries in the UFO list in the ICM cache.


Work area

Internet Communication Manager, SAP Web Dispatcher


Integer value (seconds)

Standard value


Dynamically changeable

Local and on all servers

Value Range and Syntax

You can set values between 0 and 2000000000. For most cases the standard value of 60 seconds is optimal.

SAP Recommendation

You should not set the value too high, however, as automatic expiry is the system's only way of invalidating UFO entries (since all HTTP requests that refer to UFO entries have already been rejected by the cache).
