--appended to signal the end.
multipart/form-dataand then specifies the MIME boundary string. That content-type is the default for multipart formposts but you can, of course, still modify that for your own commands and if you do, curl is clever enough to still append the boundary magic to the replaced header. You cannot really alter the boundary string, since curl needs that for producing the POST stream.
nclocally to listen on a chosen port number, change the
actionURL to submit the POST to your local
ncinstance. Submit the form and watch how
ncshows it. Then translate into a curl command line.
enctype="multipart/form-data", the first step is to find the
action=property as that tells the target for the POST. You need to convert that into a full URL for your curl command line.
action=submit.cgiis a relative path within the same "directory" as the form itself. The full URL to submit this form thus becomes
https://example.com/user/submit.cgi. That is the URL to use in the curl command line.
<input>tag used within the form, including the ones that are marked as "hidden". Hidden just means that they are not shown in the web page, but they should still be sent in the POST.
<input>in the form there should be a corresponding

@and the path to the file to include:
type="hidden". This is basically the same thing as an already filled in form field, so you convert this to a command line by using the name and value. For example:
<input>tags showed in the examples above were used in the same
<form>, then a complete curl command line to send, including the correct URL as extracted above, would look like:
