how to check for ssl.

[scotta]

I've got a section of our site where I want to force the user to 
connect via ssl.
Inside of mod_perl, is there a parameter I can grab to see whether 
the connection is ssl or not?  Or a way to get the port number?

I went through the archives last night and couldn't find anything 
near this.  Am I missing something way to obvious here? I checked 
the headers_in and nothing there would even hint that its ssl.
