Re: Problems with Intercepting WebDAV with IIS to simulate filesystem with a DB

At a basic level, I have done something similar to what you are trying to
accomplish.  If I understand you correctly, you are trying to interrogate
HTTP requests as they come into an IIS server using a IIS ISAPI filter.  I
wrote a simple ISAPI filter and implemented SF_NOTIFY_READ_RAW_DATA and
SF_NOTIFY_SEND_RAW_DATA.  I took the raw data, cast it as a string and used
::OutputDebugView to watch the requests.  Since the filter uses
SF_NOTIFY_READ_RAW_DATA and SF_NOTIFY_SEND_RAW_DATA it must be registered as
a global ISAPI filter.  Additionally you must give the directory where the
DLL resides READ & EXECUTE writes through explorer.  Ensure you give these
rights to the IWAM_XXX and I_URS_XXX user or it will not work.  If you want
to debug, you also have to make the filter low protection, which brings it
in process. Hope this helps.
