-AnonymousTicketExpiration time-in-seconds
The AnonymousTicketExpiration attribute specifies the lifespan of Session
Identifiers generated by the iTP Secure WebServer. When this period expires, the
Session Identifier is no longer valid. If access is attempted using an expired Session
Identifier, the iTP Secure WebServer issues a new ticket.
This attribute is effective only for anonymous ticketing (see Anonymous Ticketing
on page 11-1).
The Session Identifier Specification 1.0 allocates 16 bits for the expiration field. To
provide a useful set of values within these 16 bits, the content server sets expiration
times in increments of 8.5 minutes so that any expiration value between 0 and 511
results in an expiration time at the next 8.5-minute boundary. Likewise, any value
between 512 and 1023 results in an expiration time of approximately 17 minutes in
the future.
The range of expiration times is approximately 8.5 minutes to 1 year.
The following default applies:
-AnonymousTicketExpiration 21600
where 21600 seconds equals 6 hours.
To use -
AnonymousTicketExpiration in an SI_Default Region command,
enter the following:
SI_Default -AnonymousTicketExpiration 1800
-CookiePersistence time-in-seconds
The CookiePersistence attribute specifies the number of seconds that a
cookie remains valid, from the time that the cookie is issued. (The time period is
called the persistence of the cookie.)
Cookies that have a persistence greater than 0 can be stored in the web client, across
browser sessions so that sessions can continue across browser restarts, whether or
not the session is anonymous.
This attribute is effective only for anonymous ticketing (see Anonymous Ticketing
on page 11-1). For non-anonymous tickets, the ticketing agent controls how long the
ticket is valid.
The following default applies:
-CookiePersistence 0
To use -CookiePersistence in an SI_Default Region command, enter
the following:
SI_Default -CookiePersistence 1800
