SSL Environment Cache look up has been corrected so that a match
happens for this configuration.

CIRCUMVENTION FOR APAR MA42721 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR MA42720 :
-----------------------------------------------
Some old SSL implementations are not tolerant of SSL extensions.
The renegotiation indication extension was sent in TLSv1.0
client hello and the peer server failed the connection.

CORRECTION FOR APAR MA42720 :

Whenever possible, the SCSV special cipher suite will be sent
instead of the extension.  It is believed that all SSL
implementations will tolerate SCSV.
