I've been using PHP as a cgi on production NT boxes for 18 months without any problems, but I guess the traffic on these boxes would be regarded as moderate (30000 page impressions per day, all generated by PHP?MySQL or cgi stuff I wrote in C). Because IIS is a multi threaded server there are issues regarding the thread safety of some bits of PHP code. Much work has already been done to fix things but it is seriously hard stuff to debug, and there are clearly still issues which need fixing - I only we could find them! Cheers -- Phil Driscoll
