Severity: 4-Minor


The iRule command "SSL:session invalidate" allows session resumption to happen. Session resumption not supposed to occur when this iRule command is used in an iRule.


Session resumption would happen where the iRule is used with "SSL:session invalidate" included which is not supposed to occur


"SSL:session invalidate" is used in the iRule event HTTP_REQUEST


Session resumption should be disabled in SSL profiles

Fix Information

SSL::Session invalidate will now properly remove the current session information from the session cache.
