Environment Variables Editor Dialog Box

Applies To: Windows Server 2008, Windows Server 2008 R2

Environment variables are strings that contain information such as file name or path. These variables control the behavior of various programs on a computer.

When you add or edit a FastCGI application, you can define values for the application properties. For example, you can define values for environment variables. These environment variables are set by the FastCGI module during the start time of a FastCGI process. The environment variables will be set for the FastCGI process only and will not be seen by any other processes that are running on that computer. Click the Browse () button when you set the EnvironmentVariables property to open the EnvironmentVariables Collection Editor dialog box. This will let you specify optional environment variables that will be set in the FastCGI executable. If any of the supplied variable names collide with existing server variables, the ones specified in this property will be used.

UI Element List

Element Name Description


Contains a list of the members in the environment variables collection. Each member consists of a name-value pair. To add a member, type a name and value in the Name Properties pane, and then click Add. To remove a member, highlight the member in the list, and then click Remove. To change the order in which these members are stored in the ApplicationHost.config file, use the Up and Down arrows. Because all name-value pairs are unique, the order will not affect functionality.


Type a unique name for the member.


Type a value for the member. This information is stored with the corresponding name in the ApplicationHost.config file.

Sort icons

Use these icons to sort the name-value collection pairs by category, property pages, or alphabetically.
