Another way is to use raw_response. This saves directly to a file, usually in /tmp and handles redirects without a problem. See Streaming Responses. Here's their example:

>> raw = RestClient::Request.execute(
           method: :get,
           url: 'http://releases.ubuntu.com/16.04.2/ubuntu-16.04.2-desktop-amd64.iso',
           raw_response: true)
=> , @request=>
>> raw.file.size
=> 1554186240
>> raw.file.path
=> "/tmp/rest-client.20170522-5346-1pptjm1"
