SSLDELAY

The SSLDELAY system initialization parameter specifies the length of time in seconds for which CICS retains session ids for secure socket connections.

SSLDELAY={600|number}
Session ids are tokens that represent a secure connection between a client and an SSL server.

While the session id is retained by CICS within the SSLDELAY period, CICS can continue to communicate with the client without the significant overhead of an SSL handshake. The value is a number of seconds in the range 0 through 86400.
