We're planning to implement SSL on one of our sites under development.
Just wondering if there will be concerns with this and what sort of issues would I need to look out for.
Planning to put SSL once the site is completely finished.
You need to make sure that your templates don't send both HTTP and HTTPS requests, other than that your good. I would however update your login page to and admin/edit/online center to take advantage of SSL.
See Securing Edit and Admin folders for more information.
