I was trying to programmatically access the following url:
https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=garlic+press
$response = $client->get($url, ['proxy' => 'http://someproxy','timeout' => 10, 'cookies' => $jar]);
and I receive the following response:
It looks like my request is rejected by cloudfront.
