SAP GUI for HTML Server
The SAP GUI for HTML is driven by the SAP Internet Transaction Server (ITS). The ITS
interfaces between a ‘stateless’ Web server (HTTP protocol), which communicates with Web
browsers via single request/response cycles, and a ‘stateful’ R/3 System (SAP GUI protocol),
where running business transactions depends on internal status.
The ITS supports standard Web servers such as the Microsoft Internet Information Server (IIS)
and the Netscape Enterprise Server (NES).
