Overview

DATA frames convey arbitrary, variable-length sequences of octets associated with a stream. One or more DATA frames are used, for instance, to carry HTTP request or response payloads.

DATA frames MAY also contain padding. Padding can be added to DATA frames to obscure the size of messages.
