The name of a property that specifies whether to reuse previously
authenticated session information. The property contains "true" if the
mechanism implementation may attempt to reuse previously authenticated
session information; it contains "false" if the implementation must
not reuse previously authenticated session information. A setting of
"true" serves only as a hint: it does not necessarily entail actual
reuse because reuse might not be possible due to a number of reasons,
including, but not limited to, lack of mechanism support for reuse,
expiration of reusable information, and the peer's refusal to support
reuse.
The property's default value is "false". The value of this constant
is "javax.security.sasl.reuse".
Note that all other parameters and properties required to create a
SASL client/server instance must be provided regardless of whether
this property has been supplied. That is, you cannot supply any less
information in anticipation of reuse.
Mechanism implementations that support reuse might allow customization
of its implementation, for factors such as cache size, timeouts, and
criteria for reuseability. Such customizations are
implementation-dependent.
