This webpage has a redirect loop rails 3

Question

I have a problem with logging into the admin part of site of spree. I set up a subdomain www.bwscatalog.bestwatchsource.com and it works fine, but when I try to login into the admin side, I got this error:

This webpage has a redirect loop

www.bwscatalog.bestwatchsource.com/admin is hosted on a2 shared hosting. (Rails 3, Passenger)

Looking at your server's response headers, it's being constantly redirected from HTTPS to HTTP and back. Probably something within your application controller. I'm not familiar with Spree, but can you enable HTTPS for your entire site?
