When the ICM Server Cache (ISC) is being searched for a requested object, the following steps are taken, in this order:
● First the UFO List is checked to see if this request has already been rejected once by the system and is to be rejected again.
● The application then looks in the Main Memory of the ICM server cache (Memory Cache), and icm/HTTP/server_cache_<xx>/memory_size_MB establishes the size of the part of the ISC in main memory.
● The application then looks for the object in the File on the hard disk that the ISC is using (Disk Cache). The parameter icm/HTTP/server_cache_<xx>/size_MB establishes the total size of the ISC (a part of which is instantly accessible as it is stored in main memory).
