/**
* Type of data that is being written to the client (application)
* - data written can be either BODY or META data
* - META data is either INFO or HEADER
* - INFO is meta information, e.g. not BODY, that cannot be interpreted
* as headers of a response. Example FTP/IMAP pingpong answers.
* - HEADER can have additional bits set (more than one)
* - STATUS special "header", e.g. response status line in HTTP
* - CONNECT header was received during proxying the connection
* - 1XX header is part of an intermediate response, e.g. HTTP 1xx code
* - TRAILER header is trailing response data, e.g. HTTP trailers
* BODY, INFO and HEADER should not be mixed, as this would lead to
* confusion on how to interpret/format/convert the data.
