mod_rewrite...https index page -> http index page

My apologies, this is not strictly PHP...but it is relevant to a great number of PHP application frameworks that many of us use or will use. I have a Magento installation that relies heavily on mod_rewrite. For the most part, I have all of my canonical URLs worked out, minus one issue. How do I make sure that https:// requests for / are redirected to http:// / ? I've got a rule already that strips the index.php off of requests, so I don't want to check for that...just want to check for requests for the https:// version of my root home page and redirect to the non-secure version. I suck with regex and all of my attempts to modify examples I've found have failed. -- John Corry PHP developer - 3by400, Inc http://www.3by400.com
