html - What is the boundary in multipart/form-data?

I want to ask a question about the multipart/form-data. In the HTTP header, I find that the Content-Type: multipart/form-data; boundary=???.



Is the ??? free to be defined by the user? Or is it generated from the HTML? Is it possible for me to define the ??? = abcdefg?
