Content-type: multipart/form-data - how is boundary computed

[Pascal Steiss]

Hi All

When my Webbrowser sends (POST) something like

Content-Type: multipart/form-data; boundary=---------------------------
265001916915724

Is this boundary just some random value or what is it?

Thanks
Pascal

Yep, it's a random string that is used to separate the parts in a
multipart message.

The only real requirement is that the boundary string doesn't occur
anywhere in the real data that you're sending.

See the MIME RFCs for details.
