I have set the secure URL in the General > web tab under the configuration screen
This presents me with a page with style sheets being delivered using http not https, if I change the media, js and skin non secure folder setting to point to the https (replacing the non secure delimeter with the secure URL) this brings through the style sheets etc using ssl.
However when I go to the cart page I get an infinate redirection loop.
I have tested with a 100% clean install and am still getting the same issue, I am hosting on an nginx platform and not sure if there are additional steps that may need to be taken
