Hello,
I am using IIs 5 on windows 2k sp2 with php 4.1.1.
There is a problem with the sctipt that follows and MSIE versions 5 to 6
Here is the description.
A script sends a jpeg image to the client. It goes like this:
------------------------------------------------------
$imgsrc = 'full path of the image file';
....
header ("Content-type: some/image");
header ("Content-disposition: attachment; filename=myimage.jpg");
header ("Content-length: ".filesize($imgsrc) );
$fp = fopen( $imgsrc, "rb" );
if( !$fp ) {
$gError->Create( 'photodl.htm', 0, "Unable to open existing file:
$imgsrc");
$gError->ErrLog();
exit;
}
fpassthru ($fp);
exit;
------------------------------------------------------
It works fine if the user desides to save or open the image.
But if the user cancels the download, Internet Explorer stops
stops receiving anything from the site. Any click on a link hangs
when IE displays in the status bar "Web site found. Waiting for reply"
It does not hang completely. Links to static html files on my web server
work
and you can also browse any other sites, but nothing on my site that is
parsed by
php works.
After some attemts (clicks and reloads), IIs reports the following message:
"HTTP 403.9 - Access Forbidden: Too many users are connected
Internet Information Services"
Increasing the user limit on IIS, just requires a few more atemts to show
this message.
After I close all IE instances or restart IIS, everything works fine again.
I have tried ignore_user_abort, sending expire headers, readfile instead of
fpassthru etc but the problem persists.
Nothing changes with older versions of php or IE.
This problem does not happen when using Netscape (any version).
Similar script written in perl does not have the same problem.
Please help. It is a very-very late to switch to another scripting language
for
this project (even using perl or asp for the download part) requires a great
deal of work.
