The extensions seem to break under so many conditions that it's just plain ridiculous. Add in trying to support older clients and life becomes very "interesting".
Finally, I work out *most* issues under http. But now, I'm frying my head on https issues that seem to occur completely randomly.
Page 1. View source. OK, Works. Page 2, view source. Hmm fried. Practically no real difference in the structure or HTML used.
Of course, both work in FireFox, so there's no point turning on the "Live HTTP headers" extension.
My guess is that IE is, once again, adding to the pain.
back to debug mode...
