erm.. referrers and web mail

[Gadi Evron <ge () linuxbox org>]

I've been watching referrers to some web sites recently.. well, I 
encountered an old-new issue (old because it's old, new because people 
are still silly and we can call everything new in this industry).

When following URL's from web-mail, with enough lack of security I can 
access user accounts.

Gmail seems to not allow this.. others demand I login. When I checked 
some Yahoo! referrers though...
"Your login session has expired."

I wonder if I should spend some extra time and follow the next Yahoo 
mail referrer in real time? :)
