Reported By: [EMAIL PROTECTED]
Status: Bogus
Bug Type: Session related
PHP Version: 4.2.3
New Comment:
it is due to IE being to fast in disposing non-cacheable files
the temporary file that the plugin is supposed to open
doesn't exist anymore when the plugin initializes as
IE has already removed it
you can work around this by setting the session.cache_limiter
parameter to "private" to allow client side cacheing

It's some IE bug. Not PHP problem in any case.

Hi,
<?php
$a = var_export( $_SERVER, true );
session_start();
$f = fopen( "toto.txt", "a" );
fwrite( $f, "=======================\n$a\n" );
fclose( $f );
$len = filesize( "fl.pdf" );
header( "Content-Type: application/pdf" );
header( "Content-Disposition: inline; filename=fl.pdf" );
header( "Content-Length: $len" );
readfile( "fl.pdf" );
?>
When I ask for this page from IE 5.5 -> 6.0 the script is executed 2
times.
The file toto.txt contains :

With Mozilla 1.1, it's not the case.
