Ugh, I didn't know that about session handling.<p>As a tangent: guys, current ecommerce packages really, really suck. I've had a couple of ecommerce jobs recently, and for one client in particular, had to evaluate most of the field of both free and commercial offerings. They're almost uniformly <i>horrible</i>. Is there anybody willing to take a crack at doing it better?<p>I suggested round-robin DNS over a reverse proxy because reverse proxies (and similar services, like OpenBGPd) still have a single point of failure in the front-end. No matter what you do, it can still go down, and then all that back-end redundancy does squat.
