Response header
Not all headers appearing in a response are categorized as response headers
by the specification. For example, the
Content-Type
header is a representation header
indicating the original type of data in the body of the response message (prior to the encoding in the
Content-Encoding
representation header being applied). However, "conversationally" all headers are usually referred to as response headers in a response message.
The following shows a few response and representation headers after a
GET
request.
