how to avoid sending user-agent header?

[oprogramador]

In unirest, when I don't specify user-agent header, it's just not sent. However superagent sends node-superagent/5.0.2.

.set('user-agent', undefined) fails with TypeError [ERR_HTTP_INVALID_HEADER_VALUE]: Invalid value "undefined" for header "user-agent"

.set('user-agent', '') sends { 'user-agent': '' }

.set('user-agent', null) sends { 'user-agent': 'null' }

@niftylettuce Not familiar with codebase much, but after digging a bit, it seems like user-agent is set here and here(for redirects). Do you suggest we remove those calls to resolve this issue?

[niftylettuce]

Yes, I am completely OK with removing the user-agent added altogether.

Please submit a PR

.unset('User-Agent') would have worked

This should be in the docs so users know they must explicitly set a User Agent as some CDNs block requests without it
