|UFO list (BC-CST-IC)|
Unfound objects (UFOs) are URLs that the ICM server cache does not recognize or regards as invalid.
UFOs are stored in the UFO list.
The purpose of the UFO list is to provide a record of all HTTP requests that have previously been rejected by the system. This means that these requests can be identified and rejected in the future without additional load being placed on the application server (sporadic errors, denial-of-service attacks).
