Downloading a file with Range in a loop creates too many tcp connection

[Anan5a]

I'm trying to download partial content of a file inside a loop and process that. But it creates so many tcp connection that the Remote server denies the request.
My code is like this

...
while(!$ended){
$resp = $client ->get($url,[
'headers'=>[
'Range'=>"bytes=$start-$end",
]
]);
process($resp->getBody()->getContent());
}

How to solve it so it doesn't bomb the remote server with requests?
