DcsvIo.D2.Headers.Http

D2 wire-protocol headers for the HTTP transport. Includes HTTP-only entries (Authorization, Idempotency-Key, X-D2-Client-Fingerprint, X-D2-Internal-Token) and cross-transport entries (x-d2-context, traceparent, tracestate) at identical wire values. Codegen-emitted from the headers contract spec via DcsvIo.D2.Headers.SourceGen (filtered with applicability.Contains("http")). Mirrors the TypeScript package @dcsv-io/d2-headers-http at byte-equal wire values; parity is asserted by shared contract tests.

Install

dotnet add package DcsvIo.D2.Headers.Http

Public API

Member Type Purpose
HttpHeaders.AUTHORIZATION const string "Authorization" RFC 6750 bearer token header
HttpHeaders.CLIENT_FINGERPRINT const string "X-D2-Client-Fingerprint" Client-computed device fingerprint
HttpHeaders.IDEMPOTENCY_KEY const string "Idempotency-Key" Stripe-style request-deduplication key
HttpHeaders.INTERNAL_TOKEN const string "X-D2-Internal-Token" Boundary-acquired internal token (host hop)
HttpHeaders.PROPAGATED_CONTEXT const string "x-d2-context" Base64url-of-JSON propagated context envelope (cross-transport)
HttpHeaders.TRACEPARENT const string "traceparent" W3C Trace Context (cross-transport)
HttpHeaders.TRACESTATE const string "tracestate" W3C tracestate (cross-transport)
HttpHeaders.AllHttpHeaders IReadOnlyList<string> All wire values in constName order

When to reach for this catalog

Use DcsvIo.D2.Headers.Http from any HTTP-context consumer — host JWT middleware, outbound token-exchange clients, ASP.NET CORS configuration, idempotency middleware. The catalog includes both the HTTP-only entries and the cross-transport entries that an HTTP pipeline can encounter; one using covers everything.

Spec contract

The headers contract spec is the single source of truth. Every entry whose applicability array contains "http" lives in this catalog. Cross-transport entries also live in DcsvIo.D2.Headers.Common and every other transport catalog they apply to, all at identical wire values (codegen-guaranteed and verified by header catalog consistency tests).
