Application Server provides an in-process HTTP server as Web server functionality. The in-process HTTP server is Web server functionality provided in the J2EE server processes. Since the J2EE server processing receives the HTTP request directly without passing through the Web server, you can use the Web server functionality with better processing performance than during the Web server integration.

The following table lists the functionality and the reference sections corresponding to the functionality of the in-process HTTP server:

Note that the in-process HTTP server functionality provided in Application Server includes a functionality wherein the functions unique to Application Server are extended beyond the functions defined in J2EE, and also those provided as functions unique to Application Server. For details on whether the functionality is unique to Application Server, see 1.2 Functionality corresponding to the purpose of the system.
