favicon

I have two adress to my blog, one is the URL (www.aspenback.se/blog) and the other is a forward adress (blog.aspenback.se).
My problem is that my favicon (the little icon that you se in front of “http://”) does’nt show if I type in the forward adress blog.aspenback.se it’s only show if i type in the URL adress www.aspenback.se/blog. Is there any code string that I have to change or add?

This is picture of it:

This is the adress without the favicon
