Hi,
you can that a look at the REFERER header... but some browsers don't
include it and is very easy to modify...
If it isn't a problem for you, add the site id to the link:
http://my.site.com/exchange?site=friend
...this tell's you the ID, but someone can enter it directly in the
browser, too :)
Search this months archive for REFERER and you'll find some solutions,
but none is bullet proof, IMHO.
Good luck :)
