#19450 [Com]: GET request duplicated (SESSION+PDF+INTERNET EXPLORER)

ID: 19450 Comment by: richard at izyn dot co dot nz Reported By: frederic dot surleau at atosorigin dot com Status: Bogus Bug Type: Session related PHP Version: 4.2.3 New Comment: I was generating PDFs dynamically and opening them in a new window using IE6. When I changed to using sessions the file download dialogue would appear and then exit when a button was clicked with no PDF opening or being saved. The work around solved this problem. Previous Comments: ------------------------------------------------------------------------ [2002-09-17 10:37:37] hholzgra@php.net 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 ------------------------------------------------------------------------ [2002-09-17 08:09:13] sniper@php.net It's some IE bug. Not PHP problem in any case. ------------------------------------------------------------------------ [2002-09-17 06:34:53] frederic dot surleau at atosorigin dot com 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.
