Description
Description
Use the SK_CacheExpiration directive to indicate the time period, in seconds, for
which each of the entries in the session key cache is valid. This value
(time-in-seconds) is set for each entry when the entry is first added to the cache.
The expiration time can be set to a maximum of 24 hours (the default). If you set the
time to more than 24 hours, a warning message appears and the actual expiration time
is reset to 24 hours.
The iTP Secure WebServer removes an entry from the session key cache if the entry’s
time has expired or if the cache is full, in which case all expired entries are removed.
Only a positive integer is accepted as a valid value. If you set an invalid value, the iTP
Secure WebServer prints an error message during configuration-file processing, and
startup fails. If you set the value to a negative integer, an error message is printed.
Setting the value of either SK_CacheExpiration or SK_CacheSize to 0 disables
session key caching. Note, however, that a warning message is printed if only one of
these configuration directives is set to 0. Therefore, to disable session key caching,
you should set both directives to 0.
Default
SK_CacheExpiration 86,400
which assigns 24 hours, measured in seconds.
The default value is used if you do not specify SK_CacheExpiration in the
configuration file.
Example
SK_CacheExpiration 100
This example sets the cache-expiration time to 100 seconds.
SK_CacheSize
Syntax
SK_CacheSize size
Description
Use the SK_CacheSize directive to indicate the size of the session key cache in
terms of the maximum number of entries that the cache can hold at one time.
When the iTP Secure WebServer discovers that the cache has reached the maximum
number of entries and it cannot find an entry to remove, it increments the size of the
