<div dir="ltr">Klaas,<div>Using Wireshark, I see that two TCP connections are initially made to your streaming server, but one is closed after 10 seconds. The other is used for the actual stream. I suspect that Icecast reports both connections two you, but for the purposes of bandwidth consumption you are probably safe.</div><div><br></div><div>Do double check with your own devices though, with a packet sniffer. I only tested one device. Browsers vary quite a bit in how they handle media.</div><div><br></div><div>Thanks,</div><div class="gmail_extra"><div><div class="gmail_signature"><div dir="ltr"><div>
