I've created an ISAPI Extension in Delphi which works just fine, but I am wondering if there is a best practice on how to store configuration settings? I can think of a number of ways to do this, but I would of course like to do it the best way. I might have looked in all the wrong places, but I can't find anything that helps me out...
Is an ini or xml file in the same directory as the dll a good way? Or use the windows registry? Or is is possible (and sensible) to put ISAPI Extension-specific configuration in web.config and thereby utilize the IIS Manager to configure? Or something else?
I generally use GetModuleFileName(HInstance); to find out where the DLL is stored, and keep a file there (ini or xml). It's advisable to keep it, and the DLL, out of reach of IIS so it's not accessible over a URL.
