Error description
Performance of outbound SSL connections suffers to due to lack
of re-using existing SSL session ids
Local fix Problem summary
****************************************************************
* USERS AFFECTED: All users of WebSphere Application Server    *
*                 V6.1 for z/OS                                *
****************************************************************
* PROBLEM DESCRIPTION: Outbound SSL connections are not trying *
*                      to re-use existing SSL sessions. This   *
*                      means that the handshakes must be full  *
*                      handshakes each time, instead of the    *
*                      quicker ones when re-using an existing  *
*                      negotiated session.                     *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The SSL channel is not making the right call into the JSSE
provider to trigger the re-use of cached sessions. A different
API must be used that passes along the target host/port
information so that the cache can be queried.
Problem conclusion
The SSL channel is updated for outbound connections to use the
second API that allows the session cache re-use.
