Everytime a new user goes onto your web site, a new thread is used for that user. So although at the page level, you can't start new threads, threading certainly exists in CF at the application level. > As I understand it, C++ is a multi-threaded language.

If CF needs to take into account multiple threads, then it's multi- threaded capable. :) > > Please correct me if I'm wrong. > > - Matt Small > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Monday, March 18, 2002 4:10 PM > To: CF-Talk > Subject: Re: UDF question > > CF is merely an abstraction of a crap load of C++ code. > > I agree with you on the process that happens when you define a > variable > in CF.
