>>Here's a quote from a book. "ISAPI applications can be executed by IIS in a fashion similar to CGI, but they run in the same memory space as the Web server. In fact, ISAPI applications are constructed as dynamic-link libraries that can run as much as 20 times faster than equivalent CGI applications."

>>Can someone please elaborate on the Same memory space and why that would improve performance? Also explain how ISAPI applications are constructed as dll's and how this would also improve performance.

>>I know. I know. I'm just trying to get a handle on this stuff.
