How the Queue Works

The queue is designed to hold a maximum of 300 requests. For example, if the default Web Agent configuration values were not modified, 20 requests could be sent to the Policy Server at once. An additional 300 requests could then be placed in a queue. Therefore, using the default settings, the Web Agent could support 320 requests at any given moment.

By caching user information, Web Agents can support more than 320 requests at any given moment, even if you do not modify the default configuration options. However, in almost all deployments, far fewer than 320 simultaneous requests are required between a single Web Agent and the Policy Server.

Once placed in a queue, requests remain pending until one of the following takes place:

• A socket is made available and the request is sent to the Policy Server.
• The request times out.
