Packet / SYN (from pcap)

TTL, initial window and MSS come from the raw SYN packet -- the one layer a proxy fleet can't easily disguise, since it describes the kernel that opened the socket. Best-effort: requires a capture covering this connection's timestamp.

Response headers are what the handler explicitly set. Content-Length and Date are added by Go's HTTP stack directly to the wire afterward and never pass back through the header map, so they don't appear here -- see Bytes for the actual byte count.

Packet / SYN (from pcap)

TTL, initial window and MSS come from the raw SYN packet -- the one layer a proxy fleet can't easily disguise, since it describes the kernel that opened the socket. Best-effort: requires a capture covering this connection's timestamp.

No self-report from this client. If it couldn't call /report itself, you can file one manually on its behalf.

Requests

Response headers are what the handler explicitly set. Content-Length and Date are added by Go's HTTP stack directly to the wire afterward and never pass back through the header map, so they don't appear here -- see Bytes for the actual byte count.
