Again using the above as an example lets explain where and why issues can be arise. SSL - The beauty of a website is that are separate requests for different data, ie. loading pictures from 3 different sources would be a request to each respective server. The result is if a we have a website that uses both SSL and HTTP traffic we know that in most cases the website will just answer the request without care of the originating IP address. However, and this is a special case, if the website/program developer checks where the requests are originating and they find that the IP are different, they may not succesfully answer those requests (this can be by design or by accident). I had 2 cases of this, in both cases it was secured medical websites that where using it as a method of protecting their data.
