Parameter Name Description Type Size
max-object-size Maximum cacheable object size in kB (1 - 2147483 kb (2GB). All objects that exceed this are delivered to the client but not stored in the web cache. integer Minimum value: 1 Maximum value: 2147483
neg-resp-time Time in minutes to cache negative responses or errors (0 - 4294967295, default = 0 which means negative responses are not cached). integer Minimum value: 0 Maximum value: 4294967295
fresh-factor Frequency that the server is checked to see if any objects have expired (1 - 100, default = 100). The higher the fresh factor, the less often the checks occur. integer Minimum value: 1 Maximum value: 100
max-ttl Maximum time an object can stay in the web cache without checking to see if it has expired on the server (default = 7200 min (5 days); maximum = 5256000 min (10 years)). integer Minimum value: 1 Maximum value: 5256000
min-ttl Minimum time an object can stay in the web cache without checking to see if it has expired on the server (default = 5 min; maximum = 5256000 (10 years)). integer Minimum value: 1 Maximum value: 5256000
default-ttl Default object expiry time (default = 1440 min (1 day); maximum = 5256000 min (10 years)). This only applies to those objects that do not have an expiry time set by the web server. integer Minimum value: 1 Maximum value: 5256000
