Rule of Thumb for Calculating (Virtual) Memory Requirement:
memory_needed = 2 * (2N + U) * M + S * 100000 Bytes
where:
N = icm/HTTP/server_cache_<x>/max_entries
M = icm/HTTP/server_cache_<xx>/max_name_len
U = icm/HTTP/server_cache_<xx>/max_ufo_entries
S = icm/HTTP/server_cache_<xx>/memory_size_MB
The memory required consists of:
The space required for the (2 * (2N + U) * M)Index; the multiplications by 2 come from the implementation. In Unicode systems, the requirement is approximately twice as high.
The space required for the actual data in the cache (images, style sheet, and so on) (S * 100000 bytes, because S is specified in megabytes)
