Hi
I really don't know where to post this question but I believe is related to JavaScript (Prove me wrong)

Question:
Let say my website is www.site.com. another website (www.example.com) uses iframe tag to load my website in their iframe using src="www.site.com"

Now, how can I detect from www.site.com that www.example.com trying to load my website from iframe tag.

possibly javascript code can handle that or I need to modify the configuration of my web server which is apache.


Thanks
Mark
