In a sub blog with domain mapping:
In domain settings:
1. Set primary domain to an http domain
2. Front end redirect should be: directed to mapped (primary) domain
3. Choose a checkbox to force ssl on a page and save changes
The result will be an infinite redirect on the page set to force ssl. The expected outcome would be for the force ssl on a page to over ride other domain mapping settings.
Say you want to set up a site with non-ssl for speed an caching but then have ssl for the cart and payment pages. Won’t work because of this bug. Crazy stuff.
