ISAPI

Hello,
I am having a ISAPI filter which uses SF_NOTIFY_READ_RAW_DATA method. But this method is not supported in IIS 6.0 version. So for solving this problem ,
I have found that,this READ_RAW_DATA method should be replaced by ISAPI Extension with HSE_REQ_EXEC_URL function.
I am a new learner of IIS and ISAPI. Kindly explain how to create a ISAPI Extension for replacing READ_RAW_DATA method. Whether I need to create a completely new DLL for extension or can include the part of the extension in the ISAPI filter itself .

What does it actually mean ,replace the READ_RAW_DATA with HSE_REQ_EXEC_URL function??

very Urjent...


Thanks in Advance.
