In most cases, HTTP is s daemon running on another server & socket. In general, requests made to the secure server start with "https://" rather than "http://".
Pretty much, you just have to make sure that your scripts are called through "https://" links instead of "http://" links. Also, you will have to make sure that there are NO "http://" links within the page (including images) that you want secured. Having any "http://" links in the page will cause the user's connection to be unsecured.
