[ale] Document contains no data

[Doug McNash]

I would get this error when I was working on a wireless access appliance
I had slapped together with iptables transparantly proxing http
traffic.  I would get a tcp connection but no data comming back. I seem
to remember I had gotten the connection tracking rule backwards, i.e.
established connections were blocked.  Fire up ethereal and see what is
really happening.
