Considering the woes that can come with installing a SSL certificate. Yesterday, we ran into an issue with a client that I wanted to note, just in case anyone else may benefit from the scenario and solution.

Scenario

We had the Magento integrated with SVN and have a post-commit hook that auto-deploys into our root directory on the server. We originally had the httpdocs folder and the httpsdocs folder mirroring each other so that the httpsdocs folder would handle SSL (https) requests and the httpdocs would handle all other non-SSL requests.

As we were installing our SSL certificate, we changed the base_url and the secure_base_url to the appropriate (specific) URLs in place of the {{unsecure_url}} and {{secure_url}} generic values. All of a sudden, as soon as SSL installation was complete, the frontend would no longer transition from the “shopping cart” (url: http://cart.crankbrothers.com/checkout/cart/) into the “checkout” (url: https://cart.crankbrothers.com/checkout/onepage/). The checkout URL would redirect back into the shopping cart.

Solution

We realized that the sub-domain and shared docroot setup (httpdocs and httpsdocs, together) could be creating the issue. Thus, we simplified our setup (cheers Eric Dennis) to make httpdocts the separate docroot for both HTTP and HTTPS requests.

Game, set, match. Problem solved. By the way, you should check out Crank Brothers for a working example

Hope this helps save time for someone else!
