IIS 7.5 Classic ASP Error handling different from IIS 6

We are in the process of migrating an ASP Classic/ASP.NET application from IIS 6 to IIS 7.5. Most things run just fine in classic mode but we are having alot of problems with how errors are handled by IIS 7.5. We do our error reporting using a classic ASP page where we capture the error information here then redirect to a page to display the error. Based on our testing both Server.GetLastError and Request.ServerVariables("SCRIPT_NAME") when accessed from the logging page do not return the error details and source. Are there other ways we should retrieve the error information on IIS 7.5 or perform the logging?

In case this helps, using freb we have noticed that IIS appears to generate a completely n开发者_如何学编程ew request then begins executing our error capturing.

Thanks in advance.

@smaclell: See http://dylanbeattie.blogspot.com/2008/12/fun-with-servergetlasterror-in-classic.html for a potential solution for you.

Here's the relevant paragraph from the article:

There was a very similar known bug in Vista which was supposedly fixed in SP1, but it looks like the same fix isn't part of Windows 2008 Server yet. There is a workaround, though - if you set the site's default error property (under IIS settings -> Error Pages -> Edit Feature Settings...) to the custom page, IIS will invoke this page whenever an error is not handled by an explicitly configured status-code handler (so your 404, etc. handlers will still work) - but for some reason, handling the error this way means Server.GetLastError() still works properly.
