Application Configuration - App Mappings Property Sheet
Use this property sheet to map file name extensions to the program or interpreter that processes those files. Mapped applications include Internet Server API (ISAPI) applications, Active Server Pages (ASP) applications, Internet Database Connector (IDC) applications, and files that use server-side include directives. For example, when the Web server receives a request for a page with an .asp extension, it uses the application mapping to determine that the executable file asp.dll should be called to process the page.
Cache ISAPI Applications
Internet Server API DLLs can be loaded and cached so that further requests can be processed without calling the application again. Most ISAPI applications (including Active Server Pages) benefit from caching. You should clear this option only for special circumstances, such as debugging ISAPI applications.
If the same ISAPI application has been loaded and cached by more than one Web site on a server, then clearing this option for the server does not unload the application from memory. You must clear this option for all Web sites that use the application. Clearing this option does not unload running applications. Only subsequent requests are not cached.
Application Mappings
The table lists the file name extension associated with an executable file and the name of the executable file. Click the Add, Edit, and Remove buttons to modify application mappings.
Note
You can set Application Configuration properties at the Web site, virtual directory, and directory level.
