I am integrating digest authentication and am seeing "entity-body" in the document below (for auth-int authentication)? Is this the HTML header and body? Or is it just the HTML header portion?

“Entity” is an HTTP concept here. The HTTP 1.1 glossary defines it as “The information transferred as the payload of a request or response. An entity consists of metainformation in the form of entity-header fields and content in the form of an entity-body, as described in section 7.”
Thus, the entity body consists, for example, an entire HTML document, from the document type declaration (if present) down to the end tag </html>. The entity headers are HTTP headers, outside the HTML document.
