title: How to use htaccess to flip from https to http
body: <p>Well I have a site that uses relative paths for all the URLs.  I just added a shopping cart so the two or three checkout pages are using HTTPS instead of HTTP.  My problem is that a user is mid way through checkout and clicks a link on the navigation or whatever it seems them to that page <em>with</em> HTTPS when it is a page that doesn't require it (and it some cases can't handle it because of external files e.g. GoogleMaps.js)</p>
