Wiresharked the thing. Here's the packet sequence it reported:
-> DNS query A
-> DNS query AAAA
<- DNS reply A
<- DNS reply AAAA
-> TCP SYN
<- TCP SYN,ACK
-> TCP ACK
-> HTTP GET
<- HTTP reply <= That's the content!
-> TCP ACK
<- TCP FIN,ACK
-> TCP FIN,ACK
<- TCP RST
<- TCP RST
So, the full traffic is 14 packet, all small (DNS, TCP handshaking) except the one HTTP reply packet containing the full website.
- londons_explore 9y agoIt's still pretty sad that so many roundtrips are necessary... One could imagine a merged DNS and TCP syn packet, which goes to a DNS server who converts it to a TCP packet, and gets forwarded to the origin server.
