LogFile: Absolute Patch of the NSA logfile basename. default: /var/nsa/nsahttp_log LogFileFormat: Selects weather the format of the NSA log file is in ASCII or Binary. default: ASCII EnableStat: Enables NSA statistics gathering default: off CacheMaxPct: The maximum amount of system memory that the NSA HTTP service will use to cache URI data (web pages), as a percentage of the total physical memory in the system. Range: 1 - 90. default: 50. CacheTimeout: If an NSA HTTP cache entry is not accessed for more than CacheTimeout seconds, the entry becomes eligible for re-use. Range: 0 - 2147483647 seconds. Default: 600 (10 minutes). MaxURIDataLen: Maximum size URI data (web page) that NSA HTTP will cache, in 1024-byte units. Range: 1 - 2147483647 (1024-byte units).
