Architecture of the SAP Web Application Server (SAP Library - Architecture of the SAP Web Application Server)

Architecture of the SAP Web Application Server

Uses

You can use SAP Web Application Server to implement both server-side and client-side Web applications. Either the development environment integrated in SAP Web Application Server or an external tool can be used to develop server applications (for example, online shops or portals). The Web sites you create using SAP Web Application Server can contain both static HTML and dynamic script code. The scripting languages supported are ABAP and JavaScript.

For information on how to create Web applications, see Creating Web Applications with Business Server Pages. The general HTTP framework that provides the required infrastructure is explained in Internet Communication Framework. This section deals with the technical architecture of the SAP Web Application Server. A basic understanding of this is a prerequisite for the other sections.

Integration

From release 6.10 on, SAP Web Application Server is a component of mySAP.com.

Functions

The description of the architecture is divided into the following sections.

Components of the SAP Web Application Server describes the following components:

The Internet Communication Manager (ICM) receives the HTTP requests from the Internet and returns the response.

The Internet Server Cache is used to cache static and dynamic contents with Web applications.

The ICM Server Clipboard is used for temporarily storing large data BLOBs (Binary Large Objects).

We then describe how you can parameterize the ICM and the ICM server cache, and monitor and administrate them from your SAP System (Transaction SMICM).

Monitoring the ICM with the ICM Monitor

If you are using several SAP Web Application Servers, you can use the SAP Web Dispatcher to forward HTTP requests to the application server.

SAP Web Application Server: Webserver or Webclient explains how the SAP Web Application Server behaves as a server and a client. This subject is dealt with in more depth in the section Internet Communication Framework.
