Isolating Applications

Isolating applications means that they run in a process or memory space separate from the Web server and other applications. You can isolate applications into one of three levels of application protection. For more information, see Application Protection in the About Applications topic. For more information about performance issues, see About Performance Tuning.

Note   Server-side include (SSI) and Internet Database Connector (IDC) applications cannot be run in a memory space separate from the Web server.

To set or change the level of application protection
  1. In the IIS snap-in, select the Web site or the starting point directory of an application.
  2. Open the directory's property sheets, and click the Home Directory, Virtual Directory, or Directory tab.

    3. If you are in the directory listed as the Starting Point directory, the Application Name box is filled in.

  3. From the Application Protection drop-down menu, select the appropriate process option.
  4. Click OK.

    5. The Web server finishes processing any current requests for the application before creating a separate process. At the next request for the application, it will run in a separate memory space.
