+Help: Write the received headers to <filename>
+Protocols: HTTP FTP
+See-also: output
+---
+Write the received protocol headers to the specified file.
+
+This option is handy to use when you want to store the headers that an HTTP
+site sends to you. Cookies from the headers could then be read in a second
+curl invocation by using the --cookie option! The --cookie-jar option is a
+better way to store cookies.
+
+If no headers are received, the use of this option will create an empty file.
+
+When used in FTP, the FTP server response lines are considered being "headers"
+and thus are saved there.
+
+If this option is used several times, the last one will be used.
