@bbockelm Actually, TLS does have some drawbacks that aren't revealed in the papers (so I'm not quite sure what they were actually measuring but I am quite sure they are the only ones who could repeat those measurements :-) Anyway, if you use TLS you can't use sendfile() nor can you use io vectors (i.e. readv() and writev()). Depending on your workload, the lack of those can increase CPU usage a significant amount. So, I think it's a bit misleading to simply say TLS is cheap. More accurately, TLS may be cheap depending on what you're doing.
In any case, I think Fabrizio should fix the url tokens anyway. Though, I agree with you, this is a security headache.
