Yes and no...

Your POST is unusual because it sends a text/plain file.
There is nothing in the HTTP protocol that mandates the use of the
HTML standard content types. However, curl assumes them by default.
Use, e.g., -H "Content-Type: text/plain" to specify the content type.

The server script may or may not verify this header

The server script probably requires this header. Probably it is not enough
to use a fixed value: you may need a separate curl invocation to get the
cookie. See curl options -b and -c.

Since that is not produced by a standard HTML form, there are probably
some client scripts for doing it. You may need some understanding of them
in order to grasp the meaning of the content and any relations it may have
with the cookie.

Option -d does not send end of lines. You need --data-binary to send them.
