Issue Installing Boost with us_ssl

I just installed boost on a Ubercart site. Everything seems to work great except for the /cart page. I have uc_ssl installed which secures all /cart/* pages (note this does not include the /cart page.. this page is unsecure). I've set Boost to cache all pages except: /cart* (so this includes /cart). My issue is when an anonymous user adds an item to the cart, they are directed to https://www.mysite.com/cart?nocache=1 (a secure page even though it's not set secure by uc_ssl). When the user clicks on a menu item of /cart, they are directed to http://www.mysite.com/cart (a non-secure version of /cart).

Am I missing a setting? Does securepages work better with Boost?

Thanks for any guidance.
