The Secure Token Handler is a special Handler that creates a token for each request and send it to the protected application. The real user identifier is stored in a Memcached server and the protected application can request the Memcached server to get user identifier.
|
|
</p>
|
|
|
|
<p>
|
|
This mechanism allows one to protect an application with an unsafe link between Handler and the application, but with a safe link between the Memcached server and the application.
