This document details the Siteminder HTTP header 'SM_TIMETOEXPIRE'
HTTP_SM_TIMETOEXPIRE: Indicates the amount of time remaining for a session.
-> Value: seconds
Release : 12.8.x
Component : Web Agent
The "HTTP_SM_TIMTOEXPIRE" HTTP Header corresponds to the 'Maximum Timeout' value of the Realm where the user initially Authenticates. The value is in seconds.
The "HTTP_SM_TIMTOEXPIRE" HTTP Header is a variable value which is calculated.
((Login_Time + Realm_Max.Timeout) - Current_Time) = HTTP_SM_TIMTOEXPIRE
The number will initially be (in seconds) [Realm_Max.Timeout - 1] and will continue to decrease in value until it reaches zero. This will indicate that the Max Timeout has been exceeded and the web agent will need to redirect the user to authenticate.
