6.3.1 Overview of controlling the number of connections from the Web client

In the in-process HTTP server, you set the maximum number of Web clients and proxy servers connecting simultaneously and control the number of request processing threads. The in-process HTTP server creates the request processing threads for the number of connections from the Web client, and therefore, the maximum number of connections from the Web client becomes the upper limit for the number of request processing threads that are created by the in-process HTTP server.

Note that the connection requests from the client are registered in the TCP/IP Listen queue and are passed to the request processing threads. The connection requests from the client exceeding the upper limit for the number of connections are accumulated in the Listen queue. When the connection requests from the client accumulated in the Listen queue exceed the specified maximum value, the client fails to connect to the server.

The following figure shows an overview of controlling the number of connections from the Web client:
