With our sites running IIS prior to 7, if someone hits a site with no SSL cert installed via https, they would see the same web page as someone hitting it via http. In IIS 7.5 that changed with bindings so now, under the same conditions, the https request gets a "Internet Explorer cannot display..." error message.

Where is this message coming from? IIS? Is there an error code associated with it? Most importantly, how can I intercept that https request and gracefully automatically redirect them to the http page? Or can I at least show a custom error page?
