Re: Prevent a ISAPI DLL to be accessed externally in IIS 6

Any way of doing this?

All this is doable on IIS, but you're going to have to either write
the software, find free software, or pay for existing software. It is
basically custom provisioning and authorization system, which can be
written and run on top of IIS.

For example, you can create a Windows user for every customer, and all
their websites are provisioned to use the same (or different)
Application Pools using that Windows user. Then, you can ACL your
ISAPI DLL by Windows user if they pay for access to it. And you can
write an ISAPI Filter which looks at REMOTE_ADDR and URL to decide
which local/remote IPs have access to which URL.

I have sample code on my blog which illustrates most of what is needed
and a sharp developer can easily develop the filter.

I'm not certain you're going to find the system for free since as you
say, one can make a good living off the system and where's the
competitive advantage by giving it away for free?
