* Implements the SSL session interface, and exposes the session context |
|
58 |
* which is maintained by SSL servers. |
|
59 |
* |
|
60 |
* <P> Servers have the ability to manage the sessions associated with |
|
61 |
* their authentication context(s). They can do this by enumerating the |
|
62 |
* IDs of the sessions which are cached, examining those sessions, and then |
|
63 |
* perhaps invalidating a given session so that it can't be used again. |
|
64 |
* If servers do not explicitly manage the cache, sessions will linger |
|
65 |
* until memory is low enough that the runtime environment purges cache |
|
66 |
* entries automatically to reclaim space. |
|
67 |
* |
|
68 |
* <P><em> The only reason this class is not package-private is that |
|
69 |
* there's no other public way to get at the server session context which |
|
70 |
* is associated with any given authentication context. </em> |
