Call a SSI on a secure site

[netroact]

How can I call a SSI on a secure site? I can post from a form to a perl script using full SSL url, but not with an include. If I don't have a SSL url for the include, the browser views it as mixed content, and not secure. If I use a SSL url, the site is secure, but I get: "error processing this directive."

i.e. Secure: https://example.com/cgi-bin/footer/footer.pl (Site is secure, but script doesn't run)
i.e. Not Secure: /cgi-bin/footer/footer.pl (Site is not secure, but script runs)

Never mind. I was using an unsecure url. I thought it automatically redirected to secure.
