ISAPI filter problem

Hi everyone,

I am trying to create ISAPI filter that will intercept incoming header from
the client and modify it.

When I create ISAPI filter using VC++ wizard
(wizard with options: use MFC, create filter only, no server extension
objects, notification priority low, filter connection type secured and non
secured and notification for incoming raw data and headers... and nothing
else)

I build the DLL without any modifications to the code, add it the website,
restart server, but the filter is still down (red arrow pointing down)

This is only the case when I use notification for incoming raw data (
SF_NOTIFY_READ_RAW_DATA) ... if I use SF_NOTIFY_URL_MAP filter is up and
running.

I know that sometimes filters stay down until they are first used so I
checked the IIS log (with IISDebug tools) and it says that there was an
Win32Error="87"

I tried on two IIS.
So what is the problem? configuration? bad wizard or what?

Thanks,
Bob

What you want to do only requires SF_NOTIFY_PREPROC_HEADERS, where you can
easily add/remove/modify headers from the client. You do NOT need
SF_NOTIFY_READ_RAW_DATA at all, so don't use it.

I'm betting your server is IIS6 and it's a clean OS install. If so, then
you cannot register for SF_NOTIFY_READ_RAW_DATA by default... which is no
problem, because 99.9% of filter writers do not need that event (your
situtation certainly does not).

When you're ready to write your custom SSL encryption or compression
algorithm, then we may talk about it.
