19.4.7 MHTML and Line Length Limitations
HTTP implementations which share code with MHTML [45] implementations need to be aware of MIME line length limitations. Since HTTP does not have this limitation, HTTP does not fold long lines. MHTML messages being transported by HTTP follow all conventions of MHTML, including line length limitations and folding, canonicalization, etc., since HTTP transports all message-bodies as payload (see Section 3.7.2) and does not interpret the content or any MIME header lines that might be contained therein.
