IIS logs 500 server error, but page displays with 200?

We have just noticed something totally bizarre with one of our Perl
scripts, running on IIS 6, Windows 2003 Server, Perl 5.8.4.

The IIS logs show 500 as the status code for every hit to this script,
but from the user's perspective, the thing works fine. (Using
LiveHTTPHeaders add-on for Firefox, I see the server is return a 200
OK status response!) So IIS is logging 500 but sending 200.

Has anyone seen anything like this? Any ideas? Thanks!

With custom Script Engines like Perl, IIS actually logs whatever the
Script Engine tells it to. By default, IIS logs a 200.

So, it looks like the Script Engine has a bug where it sends back 200
responses but tells IIS to log 500. You will need to follow up with
support personel for the specific Script Engine.
