I need to use something like a session variable to make a variable available to an 
existing form-invoked C++ program which takes as input a file being uploaded.  Is this 
even do-able ??    If so, what am I missing here ???

The C++ prog used to use the REMOTE_USER env var set by the web server but we are no 
longer doing authentication via the webserver itself, so this one does not get set, 
and I need to set something myself. The C++ prog would had been grabbing this by 
getenv("REMOTE_USER").

I was trying some php to set a session var 'UPATH' but the UPATH variable doesn't seem 
to be visible to MyCppProg.exe :

--snip--

<?php
$_SESSION['UPATH'] = 'foobar';
?>

<form enctype="multipart/form-data" action="MyCppProg.exe" method="post">
  File to Upload: <input name="file" type="file"> <input type="submit" value="Send">
</form>

--snip--

I am new to php, have been digging around on the web, and not making a lot of headway 
quickly enough, so I'm asking.

Thanks,
JB
