There are Apache2::ModSSL and Apache::SSLLookup on CPAN in case you need 
that information in a request phase prior to the ResponseHandler. 
  
I had the same problem but the machine serving the request had a reverse 
proxy in front of it.  I used the following to inject a header on the proxy:

       SetEnv SCHEME http
       SetEnv HOST localhost
       RewriteEngine on
       RewriteCond %{HTTPS} on
       RewriteRule ^(.*) $1 [E=SCHEME:https]
       RewriteCond %{HTTP_HOST} ^(.*)$
       RewriteRule ^(.*) $1 [PT,E=HOST:%1]
       RequestHeader set X-Absolute-URI %{SCHEME}e://%{HOST}e

That gives you a header containing the protocol and host.
