TABLE OF CONTENTS To get the best out of Internet Information Server (IIS) 6.0, it is recommended that you run IIS 6.0 in worker process isolation mode. This mode allows you to isolate applications from one another so that they can be secured independently and will not affect the performance of other applications. This will increase the security and availability of applications and will improve the overall performance of the IIS server.
Application Pools
Isolating Web Applications
Understanding User Impersonation
By the end of this chapter, you should have a good understanding of the benefits of using IIS 6.0 in worker process isolation mode, as well as how to implement this mode through the creation and configuration of application pools.
Worker process isolation mode works by allowing you to create application pools. An application pool is simply a group of one or more Uniform Resource Locators (URLs) or websites applications served by one or more worker processes. Because each pool uses a separate worker process, errors in one pool will not cause errors in another pool.
In worker process isolation mode, application pools provide you with the ability to configure web application boundaries, and allow you to isolate applications based on your needs. This feature not only provides more reliability in terms of application uptime, it also protects applications from each other while allowing you to have better security options when configuring different types of applications. Additionally, because requests are routed directly from the...
