HTTP Informational Response Sequence Audit API

Check informational, final and protocol-switch responses for one HTTP/1.x request exchange.

Check informational, final and protocol-switch responses for one HTTP/1.x request exchange. Supply responses in observed order from the beginning of this exchange and the client request version, Expect: 100-continue flag and offered Upgrade tokens. Each response records content bytes, trailer count, Content-Length presence and one selected Upgrade protocol or null. Repeated informational responses and unexpected 100 responses are allowed. A final response may arrive without 100. A 101 switch needs an offered protocol and, when both Upgrade and Expect were supplied, an earlier 100. Protocol names compare without case; optional protocol versions compare exactly. The input supports a single selected Upgrade protocol, not stacked protocols. Partial evidence cannot establish that a missing terminal response is absent from the completed exchange. This sequence review does not parse wire messages, check Connection options, request content, final-response body rules, intermediaries, timing or the selected protocol after a switch. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
