need help with irule for magento shopping cart

without meaning to advertise or anything the site is www.citydeals.com when you add something to your cart go to checkout, it will then ask you to login after you register (doesn't require credit card) go through this process again login and it takes you to an account profile page, we have told magento to disable this feature and allow them to continue the checkout process and this is supposed to work, however, it doesn't. when you go to the checkout process it is https. so basicly we want them to login and then just send them back to the checkout process like we have told it to.. i'm sure its probably a ssl issue since the f5's are doing the ssl offloading we did not see this issue when the actual apache servers where handling it. if this is a continual issue with magento i think we may have to go back to having ssl being handled by the servers. If this is the case how difficult is it to remove ssl handeling from the lb and have it pass through to the apache servers. I'm new at the F5's so forgive me for being a noob. i greatly appreciate your help.
