Title: How to Enable or Disable HTTP Keep-Alives in IIS in Windows Server 2003

Objective: The objective of this demo is to teach you how to enable or disable HTTP Keep-Alives in IIS in Windows Server 2003. Most Web browsers request that the server keep the connection open across multiple requests. This is referred to as an HTTP Keep-Alive. Keep-Alive is an HTTP specification that enables greatly enhanced server performance. Without it, a browser has to make numerous connection requests for a page containing multiple elements, such as graphics. HTTP Keep-Alives are enabled by default during the installation process. If enabled, Keep-Alives last for as long as the Connection Timeout setting allows. HTTP Keep-Alives are required for integrated security or connection-based authentication services. Anonymous authentication (using NTLM) requires HTTP Keep-Alives. Disabling HTTP Keep-Alives for Web sites using Anonymous authentication will cause requests to that Web site to fail.
