Old message, but didn't see this suggested, so...

There is an SSL version of Lynx.  Lynx can retrieve a web page from the
command line and output to STDOUT using the -dump option.  (There is also a
Perl library with built-in routines for accessing the same library Lynx
uses, but not sure whether that support SSL.)  So create a small file and
have your script attempt to retrieve it and look for some nice, unique
string in the file.

Hope that helps.  :)
