Parameter documentation

This parameter is only relevant if you have configured the communication between the SAP Web Dispatcher and back-end servers with SSL, that is, either the communication to the message server (wdisp/server_info_protocol = https), or the communication to the application servers (wdisp/group_info_protocol=https or wdisp/url_map_protocol=https or in accordance with wdisp/ssl_encrypt). If this parameter is not set, a server certificate must be issued for the relevant host name for each application server. You can use this parameter to specify a host, in the name of which the server certificate is issued. Then you do not have to provide a certificate for each application server. Example Your server certificate is issued for the name "www.sap.com". You activate this certificate for all application servers in transaction STRUST. You also set the value of wdisp/ssl_certhost to www.sap.com. If this parameter is not set, the host names on the message server (transaction SMLG) and the names in which the certificates are issued must be the same.
See SAP Parameter Documentation for full SAP documentation for this profile parameter.
