I disagree. I think it looks as if the server is delaying its reponse.

Three comments on this command line.

Why do you modify the Content-Length header? That just makes it more
error-prone in case you set it to a size that doesn't match the actual
contents you send. This may very well be the reason why you see this delay.

The Authorization: header is much easily set with the --user option, imho.

The Host: header is not doing anything useful in this case, as curl will add
such a Host: header by itself.

The fact that the entire request was sent off fine is why I think this looks
like one of two possible reasons:

1. You've ruined the request with a bad content-length header so that the
server is still awaiting more data even though curl is done.

2. The server doesn't like something else in this request and doesn't respond
swiftly because of this.

The "authentication header" ? That is just one line, and you've provided it
using the -H "Authorization" option. What other 5 headers are you referring
to?
