WGate (Web gateway)

WGate (for Web gateway) is one of two major components of the Internet Transaction Server (ITS) from SAP, the software company that provides a popular set of programs for managing a large enterprise. The WGate and the AGate (for application gateway) perform the tasks that enable an end user to access an SAP R/3 application over the Internet. The WGate establishes the connection between ITS and the Web server and forwards user requests to the AGate, which establishes the link to the R/3 system and performs the processing tasks required to move data between R/3 applications and the Internet. The WGate and the AGate communicate over TCP/IP using the SAP Network Interface (NI).
