[Fwd: don't want to belabor a point about session_start, but...

OK, I understand that in order to avoid those nasty warning messages about "Cannot send session cookie - headers already sent...." you must include the directive, session_start, above all headers, includes, etc. I'm trying to debug and port a contractor's code to PHP 4.3.4 from a couple of years ago. Is there an explanation as to why the code, written under PHP 3 and also working under PHP 4.0.4, would not generate these warning messages, without having session_start at the top of the file? The session_start directive is pulled in later with an include file. -- Rachael LaPorte Taylor U.S. Census Bureau Washington DC 20233 rachael.laporte.taylor@census.gov
