Probe detail

Server-observed TCP/TLS/H2/HTTP layers, joined per client. See results for the application-layer / self-reported view.

Drag the right edge of a column header to resize it (tables can grow past the screen -- scroll horizontally). Each table has Copy/Download TSV buttons above it.

Omitted entirely (only ever viewed results/detail pages, never ran a probe): curl/8.7.1

Connection comparison

TLS/H2/TCP fingerprint per client, with your own browser (the request that loaded this page) pinned at top for reference.

Test results

Hover a cell for the raw outcome. FAIL means the probe was reached but the capability wasn't demonstrated (e.g. no conditional revalidation sent); "-" means the probe was never reached.

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.

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.
