HttpsCanonical 1.0.11 Download Create rel/canonical tag to avoid google "duplicate content errors".

This simple module provides a useful feature to avoid duplicate content errors from google, which you will encounter if you provide both, http and https.

Once enabled, you can add the new "HttpsCanonical" part to any ContentItem, which will then get a "rel=canonical" tag rendered, pointing to the https-version (if the current site is http).
