Just speculating... Maybe CGI is configured to run the command line
interface, which does not generate headers :-?

Don't think so. In that case the errors would be consistent.
These errors seem to occur at random.
Thanks for the input though.

Bump.
So looking at all these replies :) there are a few possible conclusion:
-Nobody knows;
-Nobody cares;
-Nobody has site site on an Windows-based platform;
-Nobody has encountered this problem.
Maybe a few more.
So assuming the first 3 can't be true, I take it then, that the old problem
is solved in PHP 5.1.4?
If that is the case, then why are these errors occuring?

Imagine having a website with about 10% of the hits returning a 502. I've
had that a few days back. This is just disastrous....
Things are more stable now, but I am worried.
So let's be more specific.
On almost every page I have:

<?php ob_start("ob_gzhandler"); ?>

I have a stylesheet page called styles.php with the header:
<?php header("Content-type: text/css; charset=UTF-8"); ?>
Called from every page with:
<link rel="stylesheet" type="text/css"
href="http://www.mydomain.com/stylesheet.php?pageID=<?php echo $pageID; ?>">
$pageID is a variable with which I determine which colors to use. These data
are stored in MySQL.
Any flaws in this?

Thanks voor your thoughts.

I use the isapi version with Windows, and it works fine. I've been
using it since early PHP4, and have upgraded regularly (currently using
5.1.2). Used them on both W2K and W2K3.

If it's configured correctly, the only thing I've seen cause problems is
bad PHP code causing an abnormal termination of the PHP thread/process.
No, it shouldn't happen since PHP is interpreted, but it sometimes
does. And every time I've seen it happen it's been bad (invalid) code
that screws up the parser.

But again - I don't use the CGI version. It's performance isn't as good
as the isapi version, IMHO.

My suggestion - if it's not your code and your host can't get their end
working, find another host.

Yup, that's what the hoster suggested. The only thing was, that it too had
some error: it didn't recognize "mysql_pconnect".
He fixed that.

Because of the new isapi settings he also turned on some error messaging,
which revealed a mistake (I am not ready to admit that forgetting some
quotes was a blunder :) ).
But it sure wasn't the cause of the malfunction.

Thanks for the reassuring words.
We'll wait and see what the isapi setting will do.
The hosting company has an excellent helpdesk service, they helped me out
often enough and these guys are alright.

Cheers,

Spark.

OK, and BTW - I wouldn't recommend using mysql_pconnect() unless you are
doing dozens of connections per second. Otherwise using it keeps a lot
of unused resources allocated all the time.

I have yet to see a website using MySQL where mysql_pconnect() is
worthwhile. I'm sure they exist - but I haven't run into anything
nearly that heavy usage.

A standaard in dreamweaver. I never thought of looking into that. I will
though.
(Chapter 41 on php.net :) )

The site is now running flawlessly, so far...

Thanks again,

Spark.
