SICF set https as default

Hello,

does anyone know how to set https as the default protocol in SICF? I know how to setup SSL or change single services but I would like to change it for all services. For example, if I test a service in SICF, https should be called, not http. I tried to set the default_host node in SICF to SSL on the logon data tab but that did not help.

I am running a NW 7.x system.

Regards

Andreas
