Escaping SSL via dynamically generated lists in Widgets

Hi all,

I hope my title is clear enough. Here is the situation:

We run a WordPress site for a non-profit. They take donations and sell a small amount of merchandise. We have an SSL certificate, and want a secure connection on the Donation and checkout page. We have this set up and everything works great.

The problem here is that we use a custom wp_list_pages setup in the sidebar that dynamically generates links to other pages in the parent category. If someone is on the donation page and they use this menu or even a recent post widget they are linked to that page or post with a secure connection. When these pages are viewed in a secure connection, they user is warned that there is insecure content on the page.

My question is how can I escape the https:// generated by wp_list_pages from a secure page and redirect it to a normal insecure connection?
