HTTP - Body (Content, Entity, payload, data sent)

About

Entities are the data sent with an HTTP message:

  • HTML page
  • Image
  • Web form parameters

An entity is better known as the body or in a network context, this is the payload of the message.

Format

The entity of an HTTP message can have an arbitrary data format, which is usually specified as a MIME type in a header field. Accept → text/css,*/*;q=0.1 ?

Example

A response can contain:

  • the page
  • an image you are downloading as an entity,

Or a request can include the parameters that you entered into a web form.

Save or display ?

See the content-disposition header
