I am having trouble with the following function working _with_
sessions. If I turn off my session checking function it enables you to
download the file flawlessly, if sessions are turned on then Internet
Explorer displays an error:

Internet Explorer cannot download ...URL

Internet Explorer was not able to open this Internet site. The requested
site is either unavailable or cannot be found. Please try again later.

Is there a way I can download large objects from postgresql _with_
sessions? Thankyou.

function retrieve_file($id) { 
global $dbconn1; 

$result1 = pg_exec ($dbconn1, "select data, file_name from files where
$image_oid = pg_result($result1 ,0, 'data'); 
$file_name = pg_result($result1 ,0, 'file_name'); 

header ("Content-disposition: filename=\"$file_name\""); 
header("Content-type: application/download"); 

pg_exec ($dbconn1, "begin transaction;"); 
$image_handle = pg_loopen ($dbconn1, $image_oid, 'r'); 

pg_loreadall ($image_handle); pg_loclose ($image_handle); 
pg_exec ($dbconn1, "commit transaction;"); }
