Probe detail

This run is no longer active in server memory (restart or run-limit eviction) -- reconstructed from the event log on disk.

Locked -- this run no longer accepts new test activity. Everything below is what it captured before the lock.

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

Click "Headers" for the full request and response header values for that request. Response headers shown 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 won't appear there; see Bytes for the actual byte count.

Test summary

`cache_etag`	Caching: ETag conditional revalidation on a repeat fetch.	unconditional	1
`cache_heuristic`	Caching: no Cache-Control/Expires at all, only a stale Last-Modified -- tests optional RFC 7234 heuristic freshness.	unconditional	1
`cache_maxage`	Caching: max-age=3600 resource -- repeat fetches reveal whether the client caches at all.	fetched	1
`cache_random`	Caching: a fresh random number on every real origin hit -- a client-reported repeat value is direct proof of caching, no header semantics needed.	served	1
`delay_body`	Timeout: fast TTFB then a trickled body -- how long the client waits out a stalled body.	abandoned	1
`delay_header`	Timeout: stall before response headers -- how long the client waits for TTFB.	abandoned	1
`enc_br`	Compression (negotiated): returns Brotli because Accept-Encoding asked for it.	served	1
`enc_force_br`	Compression (forced): Brotli sent regardless of Accept-Encoding -- tests decode-only capability.	served	1
`enc_force_gzip`	Compression (forced): gzip sent regardless of Accept-Encoding -- tests decode-only capability.	served	1
`enc_force_zstd`	Compression (forced): zstd sent regardless of Accept-Encoding -- tests decode-only capability.	served	1
`enc_gzip`	Compression (negotiated): returns gzip because Accept-Encoding asked for it.	served	1

This client's requests carry proxy-tier headers (x-envoy-expected-rq-timeout-ms, x-request-id) — the TLS/H2/TCP characteristics above likely describe a proxy fleet in front of the agent, not the agent itself.

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

Caching: self-reported vs. server-observed

"Self-reported" is what the client believes it did (from cache_*_fetches / cache_*_conditional in its report); "server-observed" is what actually reached this origin. A gap -- more self-reported fetches than observed requests -- suggests a cache sitting between the client and here that the client itself can't see.

Probe	Self-reported fetches	Server-observed requests	Self-reported conditional

`cache_heuristic`	-	1	-
`cache_maxage`	-	1	-
