[nycphp-talk] Passing some form values through to a redirected page...

	Sessions are OK, I guess, if you really need to keep sending
the data around, but keep in mind then, that all of that POST data
will get sent back-and-forth between the server and browser for each
successive page-load.  And if you do a "Location:" redirect, that
will of course count as two page loads, so that is conceivably a
waste of time and bandwidth.  Depending how your server is configured,
the additional HTTP transaction from the server might be costly if 
you do it a lot, or if your server is already busy.

	So you said you don't want to "embed" the 2nd script into
the first one... why not just "include" it?  That way, the only
additional cost of the "redirect" is reading and executing that
file... no extra HTTP noise (which in some cases could slow things
down by more than a few seconds per page hit).

	Overall, it sounds like you might be moving toward
building one single "library" file of your functions, and then your
"scripts" would include this library and call whatever functions it

	Also, I don't know how much data is getting POSTed, but if
it's more than a few hundred characters (or has the potential to be),
you might have problems doing Location: redirects with all that data.
I could explain this further if it doesn't make sense.
