Siege Testing Your Site Behind a Login

I use Siege to test my web applications and get an idea of how much traffic they can sustain. It is a great tool and I suggest you read more about it here.

A few days ago, I needed to test a part of my application that was behind a login. I hit up UPHPU user group on IRC, and Carmony (a master website optimizer) suggested logging in on my browser and then hijacking the session in siege by setting header values. That is a great idea, but seems overly difficult. I doubted that I was the only one that ever wanted to do this. Isn’t there an easier way?
