Overview of Internet Information Services 5.0

Programmability

This section acquaints you with the new features that improve IIS programmability. For more information, see Administering an ISP Installation in this book, and the IIS 5.0 online product documentation.

Application Protection IIS 5.0 offers greater protection and increased reliability for your Web applications. By default, IIS 5.0 will run all of your applications in a common (or pooled) process that is separate from core IIS 5.0 processes. In addition, you can still isolate mission-critical applications that should be run outside of both core IIS 5.0 and pooled processes.
