Request method changed on redirect

Hi,

I’m using axios v0.17.0 with HEAD method like this:

axios.head('http://example.com');

(let’s suppose http://example.com is set to redirect 301 to http://www.example.com)

For some reason Request method will change on the first redirect to GET instead of keeping HEAD all the way down. This will read in logs like this:

example.com:80 10.0.0.1 - - "HEAD / HTTP/1.1" 301 237 "-" "axios/0.17.0"
example.com:80 10.0.0.1 - - "GET / HTTP/1.1" 200 246 "-" "axios/0.17.0"

instead of this:

example.com:80 10.0.0.1 - - "HEAD / HTTP/1.1" 301 237 "-" "axios/0.17.0"
example.com:80 10.0.0.1 - - "HEAD / HTTP/1.1" 200 246 "-" "axios/0.17.0"

When I do the test in Firefox it keeps original request method (HEAD) all the way down.

Any idea why is this?

Thanks, Milos

It turns out that olalonde/follow-redirects package is following RFC specifications which says that Request method is case-sensitive as pointed out by @RubenVerborg here but axios is passing lowecase verb head causing the wrong redirect behavior.

If your PR has a test case for this I am happy to review it 😃
