Parameter documentation

This parameter contains the official name of the application server. The application server uses this name to identify itself with communication partners (for example, for HTTP requests). You can enter any character string as the value. The HTTP server header consists of this character chain and the version specified in is/server_version. You can also suppress the specification of the server header in HTTP messages by setting the is/HTTP/show_server_header parameter to FALSE.
See SAP Parameter Documentation for full SAP documentation for this profile parameter.
