How to make a certain link of an iframe load the whole page

Example:

<iframe scr="https://www.google.com.br/?gfe_rd=cr&ei=WKaFVtKXJ8yG8Qec97KwCg#q=stack+overflow"></iframe>

  

A simple google search for Stack Overflow site

I wanted it when I clicked the link (pt.stackoverflow.com), it would load the whole page to the respective link.

In short, a certain iframe link should be loaded as a normal page (ie using refresh).
