"So either not a cache problem, or Marks & Sparks were very naughty and weren't encrypting the pages."
I heard that they were having cache <sic> flow problems but this one seems to be worse than my wildest fears.
I once asked a Scottish systems administrator how big her cache was on a support call. She heard "how big is your gash?" and I got an embarrassed reply of "no bigger than any other girl of my age". Even now I cringe at the thought.
