Also in this Section Why do I get the message 'some items are insecure'? Why do my pages load more slowly when I use SSL? I can't get SSL to work with my frame pages. Why?

There are no differences besides comestic wise.

E.g.

https://www.yourdomain.com/ (using your own SSL)
https://servername.somedomain.com/~username/ (using our SSL)
