Find out deployment type?

I can not find the answer in the documentation so probably I am searching for the wrong term. Maybe you can point me in the right direction.

When building for desktop we can do for example:
#if TargetCocoa then…

Is there a built in function so that a web-application knows if it is deployed as cgi or standalone?
For example something like:

#if Standalone then…

#if CGI then…

If App.Mode = 0 Then
// CGI
ElseIf App.Mode = 1 Then
// Standalone
End If


thanks Norman, I know that constants but I did dot find exactly what I am looking for there.
Thanks Phillip, that property seems to do the right thing!

Happy to help.

yeah I see I misinterpretted what you were looking for
