A quick Google search shows me this:

Limiting HTTP Sessions
An administrator can limit the number of active HTTP sessions based on detection of a low-memory condition. This is useful in avoiding out of memory exceptions.
WebLogic Server refuses requests that create new HTTP sessions after the configured threshold has been reached. In a WebLogic Server cluster, the proxy plug-in redirects a refused request to another Managed Server in the cluster. A non-clustered server instance can re-direct requests to alternative server instance.
The servlet container takes one of the following actions when maximum number of sessions is reached:
If the server instance is in a cluster, a 503 response is sent back. The behavior after this response is sent is determined by your load balancer or proxy server.
You set a limit for the number of simultaneous HTTP sessions in the deployment descriptor for the Web Application. For example, the following element sets a limit of 12 sessions:
<session-descriptor> <max-in-memory-sessions>12</max-in-memory-sessions> </session-descriptor>
