Web Tier Socket Usage

When a Web Agent starts, it opens the number of sockets specified by the MinSocketsPerPort parameter in the Host Configuration Object on the Policy Server. If more requests are received, the Web Agent adds a specified number of new sockets to the connection pool until the maximum number of sockets is reached. When all sockets used, any additional requests (up to 300) are held in a queue, until one of the following events occurs:

• A socket pair becomes available and the request is sent to the Policy Server.
• The request times out, and the user must try again to access the resource.

The following illustration describes this process:

The Host Configuration Object on the Policy Server contains the parameters that control the number of sockets used.
