Remarks

The protocol property specifies how to transfer information from the host to the client. Microsoft® Internet Explorer supports several predefined protocols , including http and ftp .

The document , img , and location objects expose the protocol property as read-only. location . protocol property returns the initial substring of a URL, including the first colon (for example, http: ). However, document . protocol returns the expanded text of the protocol acronym. For example, it returns the http protocol as Hypertext Transfer Protocol.
