ISAPI plugin for IIS , Servlets FAIL on dual Processor NT Machi nes

[Gerard Horan <ge...@clarent.com>]

I have been debugging jk_isapi_plugin.c in the isapi_redirect.dll

Problem: When we run our servlets on a DUAL Processor NT
machine using IIS + isapi_redirect.dll + Tomcat they fail since the Filter 
does not get properly redirected.

I have tracked it down to an Assumption in the code that the thread that
executes the HttpExtensionProc and the HttpFilterProc are different. On
single processor machines  IT IS ALWAYS the same thread. TLS (Thread Local
Storage) is
used to pass data from HttpFilterProc to  HttpExtensionProc. Since we cannot
depend
on the same thread being run, TLS is not a valid means to store/pass data.

Does this make sense? Have I made a configuration error?

Any pointers appreciated

regards
