Previously on this list, there have been questions about the Warning: page
has expired problem. When you submit a form, then press the back button, you
get this message and have to press refresh before the page will redisplay.
I have discovered that if you use the following header command, the problem
does not occur.
header("Cache-Control: public");
The back button takes you back to the form, without a warning message, and
the form redisplays with the info you entered. Does anyone know a reason
that the above header should not be used? Does it cause some sort of problem
that I should be aware of?
