Request path

Type a file name extension or file name with an extension for which you want the handler to process requests. For example, if you want the handler to process all requests made for files with the extension .abc, enter *.abc; or if you want the handler to run all requests made for a specific file, enter the file name and its extension, such as Myfile.abc.

Module

Select the module that you want to process requests for resources specified in the Request path box.

Executable (optional)

Optionally, type a path to the .dll or .exe file when the module you selected in the Module box requires an executable to run, such as the FastCGI module.

	Note
	After you click OK to add or save the handler mapping, the executable must be added to the ISAPI and CGI Restrictions list to enable it to run.

If you specify a .exe file, you can also type optional command-line parameters after the path. Command-line parameters are not supported for .dll files.

	Note
	If you specify a path for a .exe file, and the path contains spaces, you must enclose the path with double quotation marks ("). For example, type "c:\files\handler files\handler.exe". This is not required for .dll files.

Name

Type a descriptive friendly name for the handler mapping.

Request Restrictions

Opens the Request Restrictions dialog box from which you can specify additional, optional restrictions for the mapping.
