http:response-body object[Generic Function]

Reader for the HTTP response body. If the body is nil then a body is not sent with the reply. The response body may be a vector or a list of vector chunks with each chunk being either a vector or a list of the vector and an optional start and end position. The body of a sent response will contain only octet byte vectors, however the server accepts strings for the response body which will be converted into byte vectors when sending the response. The body of a HTTP server response may also include stream sources or a file descriptor to splice with the connection stream, see http:make-response.
