Isn't this strange that the customer_id field doesn't have a value? Or is that
taken care of with cookies?

It certainly looks like a correct curl command line using -F.

What doesn't work with this usage?

When it comes to -F uploads, I've noticed on several occations that sites tend
to do the most stupid checks of the data format. For example, starting with
curl 7.10.5, we "clone" the IE look for the "part separation strings" as many
sites can't deal with the boundary string curl used in previous versions.

I've also seen sites that refuse to accept file uploads in case the file name
doesn't start with "[LETTER]:" etc...

So, figuring out exactly where the problem is can be hard.
