[tan hai shi]

Hi,

I'm half way configure Tomcat integration with IIS following Gal Shachor step-by-step 
instruction.
I'm not able to understand where can i add filter in IIS for
isapi_redirect.dll.  I need further clarification on the above mentioned.
I'm currently using IIS4 with NT SP4.
Thanks in advanced.
