ThinApp User’s Guide : Configuring Package Parameters : Configuring File and Protocol Associations : Protocols

The Protocols parameter specifies the protocols, such as HTTP, that are visible to applications in the physical environment. This parameter is similar to the FileTypes parameter, but deals with applications that handle protocols rather than file types.
The capture process generates initial values that you cannot add to. You can remove entries for browsers or other applications.
The capture process can specify protocols, such as the mailto protocol for a Microsoft Outlook package, in the Protocols parameter.
