Secure server path

I would like to make my site secure. However when I try to secure the media directory the certificate won't go away. I am using https://www.langdell.uk.com/computers/etc... . Please will you tell me the URL to make all of the following secure:

Main Site
Administration Area
Media Directory

Certificate Appearing For Each Media File

The problem mentioned above appears to be due to the certificate appearing for each media file that downloads. How will I circumvent this problem? I want the certificate to appear once when I am accessing the administration area.

Sussed the problem

I have now fixed the certificate problem by putting the admin folder into the private area.

Regards,
