I'd like to take this time to show some love to ISAPI extensions and filters. Wrote some kickass stuff with that technology about 15 years ago (in Delphi of course).
I recall using some open source Delphi software that allowed auto reload of an ISAPI.DLL just by replacing the DLL in the folder. That saved an iisreset. Never got a chance to thank the technical wizard that created that.
Damn that's sweet. I remember all the IIS restarts. Prolly in the 100's.
