What is MIME type "application/set-registration-initiation"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/set-registration-initiation is a specialized MIME type. It signals that a file carries data to start a registration session for an application or service.
It defines a message format that instructs an endpoint to begin a structured registration process.

This type often appears when secure or automated registration is needed. The file content contains parameters and instructions for the initial handshake between a client and a server.

• Initiates registration: It triggers the starting phase of setting up an account or service connection.
• Automates enrollment: It supports systems that need to auto-configure new registrations.
• Enhances security: The initiation data can include parameters that help verify and secure the enrollment process.

Files using this MIME type usually have the extension SETREG. This association helps systems recognize and process them correctly.
