i have experienced the same problem with IIS, however upgrading (and it
definitly IS an upgrade) to apache is not possible since i have production
servers running IIS and no person to run apache that can do it in a
production environment - my solution is to use CGI instead of ISAPI - it's
not the schweeet low level access that ISAPI provides, but I don't think the
ISAPI php lib is stable enough yet to use in critical apps - most have
better running php as CGI.
just my 2 sense of it.
