This question comes up frequently in the group since MS has a hard time
following anyone's standard other than their own. The trick is to add this
line to the top of your program.
_____
<?php header("Cache-control: private"); ?>
<html>
<head>
...
Note that the opening PHP tag is on the first line, first character position.
If you fail to do this, you will run into another set of errors that say, in
effect, "Can't write the headers because the headers have already been sent."
You need to do any header work (including cookies and session variables) before
you start to output any HTML to the program. This is the HTTP head (not the
HTML head) that contains header() statements, setcookie() statements and any
references to write to sessions.
Good luck.
