ISAPI Filter not communicating with Extension.

[Frank Diakovasilis <fd...@lexel.com>]

I am having an issue with the isapi redirect (versions 1.1 & 1.2) with
Tomcat 4.x on windows 2003.  The filter seems to fail in redirecting to the
extension.
 
When working properly the logs show that the filter transfers the data to
the extension fine.  When not working properly the logs show the filter
trying to transfer control, but what happens is the the filter gets
re-accessed this time trying to parse the redirect's uri
(/Redirect/isapi_redirect.dll).  Below is a log of the failed attempt.  Is
this due to the nature of these ISAPIs using Thread Local Storage (TLS)?
This anomaly occurs on one version of 2003 but not another.
NOTE: the aliasing/permissions are correct and the extension is registered
as a web service on IIS6.
