Thanks for the mail, Andrew.
I'm not sure I'm reading this correctly. Some responses from my host
appear to happen in a very short period, while others seem to take a bit
longer.
Its not clear to me why lfallback2's connection at 12. requires 3
different connections from my host (13-15).
Enlightenment much appreciated.
Rory
