 For non-HTTP protocols like FTP, POP3, IMAP and SMTP this function will get
 called with the server responses to the commands that libcurl sends.
+.SH LIMITATIONS
+libcurl does not unfold HTTP "folded headers" (deprecated since RFC 7230). A
+folder header is a header that continues on a subsequent line and starts with
+a whitespace. Such folds will be passed to the header callback as a separate
+one, although strictly it is just a continuation of the previous line.
 .SH DEFAULT
 Nothing.
