Use the Handler Mappings feature page to manage a list of handlers that process requests for specific file types.
Sort the list by clicking one of the feature page column headings or select a value from the Group by drop-down list to group similar items.
UI Element List
The following tables describe the UI elements that are available on the feature page and in the Actions pane.
Feature Page Elements
Displays the name of the handler mapping.
Displays the file name or file name extension for which the handler will process a response. The value can be either a specific file name, such as WebResource.axd, or a wildcard (*) with a specific extension, such as *.exe.
Displays whether the handler is enabled or disabled based on the access policy set in the Edit Feature Permissions dialog box and the required access setting specified by the handler mapping. If a handler requires a type of access that is not enabled in the access policy at that level, the handler is disabled.
Displays one of the following values for the type of path to which the handler is mapped:
Displays the module, such as IsapiModule, or managed type, such as System.Web.Handlers.TraceHandler, that responds to the request as specified in the mapping.
Displays whether the item is local or inherited. Local items are read from the current configuration file, and inherited items are read from a parent configuration file.
