icm/HTTP/server_cache_<x>/max_entries 

Maximum number of entries in the ICM/HTTP server cache (see the documentation on icm/HTTP/server_cache_<xx>).

When dimensioning, make sure that the memory requirement for the cache entries does not clash with the setting for the parameter icm/HTTP/server_cache_<xx>/size_MB. A rule of thumb for memory use is given in the documentation for this parameter.
