a multipart/form-data is selected with the -F or --form option.

Problem 2 is an illegal hex value received from the server. It's almost
definitely a server problem. But it's surprising it's not working, because
the -T option overrides -d and this command ends up doing a PUT, not a POST.
Try replacing all the -d with -F to start. You'll probably also want to
remove the name=file_1 option and replace it with -F file_1=@${HOME}/test.txt

Note that you can use the --trace-ascii option in curl to get trace output
that you can compare with LifeHTTPHeaders to see where things are going
wrong.
