And where does IE write them? What do you mean by 'empty session files'? As PHP is server-side, it's a bit impossible
to be browser that causes this behaviour.

Do you have any short example code of this?

It isn't the browser that causes this behaviour, it's the protocol. When a php script that uses sessions is requested using HTTP/1.0, created session files are empty. When the same script is requested using HTTP/1.1 everything works fine.

Sample url: http://www.hi-technet.com/php/count_me.php
Sample code:

<?
session_start();

echo session_id();

if(!isset($count)) {
  session_register("count");
  $count = 1;
}
else {
  $count++;
}

echo "<p>You've been here $count times.  Thanks!</p>";

?>

This works for me just fine with PHP 4.0.6RC3.
Could you please try it? You can find it here:

Hi,

I've tried to get sessions working with version 4.0.1pl2 and version 4.0.5. What is the chance it will work with this release candidate? Isn't there another way to verify this problem? Can you change the description of this bug?

If you don't want to test it, it's your problem. 
This works for me just fine as it does for hundreds of
other people too. Check your settings.

We aren't making any progress this way.
First, there are many people with empty session files.
It isn't just me.....
Like you said, it works just fine for me.
Not for everybody.
I simple can't install new software just like this.
There are many sites running on that server.
I rather not risk downtime. So, please give me a better reason then, "please try it"!
