HTTP Accept Parser Parse media ranges, parameters, and q weights in Accept without collapsing order or choosing a representation.
HTTP Accept-Language Parser Parse RFC 4647 basic language ranges and HTTP quality weights while retaining header order.
HTTP Age Delta Seconds Parser Parse HTTP Age delta-seconds as unsigned decimal; retain exact spelling-normalized value and conservatively saturate numeric age at 2^31 seconds.
HTTP Basic Authentication Parser Decode strict Base64 Basic credentials as byte values and separate the first colon, leaving character-set interpretation to the caller.
HTTP Bearer Extractor Extract one Bearer credential from an Authorization field, rejecting line breaks and malformed token characters.
HTTP Content-Disposition Parser Parse a disposition type and unquote its parameters, preserving RFC 5987 extended values for caller interpretation.
HTTP Content-Type Parser Parse an HTTP media type and its parameters, preserving parameter values and rejecting duplicate names.
HTTP Cookie Parser Parse a Cookie header into ordered name and value pairs while preserving duplicate cookie names and encoded values.
HTTP Cookie Serializer Serialize ordered cookie pairs using RFC 6265 cookie octets without implicit escaping or decoding.
HTTP ETag Parser Parse one HTTP entity tag into its weak/strong flag and opaque value; rejects lists and unquoted values.
HTTP Forwarded Parser Parse RFC 7239 Forwarded elements into ordered parameter lists without inferring proxy trust or validating addresses.
HTTP Header Line First Colon Splitter Split one HTTP field line at its first colon, validating a nonempty token name while retaining raw value whitespace; CR/LF or obs-fold are rejected.
HTTP Header List Combination Plan Plan comma combination only for explicit caller-qualified list fields, always preserving Set-Cookie as uncombined; no universal field-combination inference.
HTTP Header Name Normalizer Validate an HTTP field name as an RFC token and convert it to lowercase for case-insensitive lookup.
HTTP Header Occurrence Byte Budget Budget HTTP/1 field section octets under literal name-colon-space-value-CRLF serialization plus final CRLF; Latin-1 octets, not HTTP/2 compression or UTF-8.
HTTP Header Occurrence Case Collisions Audit HTTP field-name spelling collisions separately from repeated identical spellings; validates token names and Latin-1 field-value octets.
HTTP Header Occurrence Name Groups Group all HTTP field occurrences under ASCII case-insensitive names while retaining raw ordered occurrences; no list combination or deduplication.
HTTP Header Occurrence Order Map Map explicit field occurrences to stable canonical-name ordering and within-name ordinals without serializing or reordering a request.
HTTP Header Occurrence Selector Select all explicit HTTP header occurrences by a token-name bank under case-insensitive lookup, retaining source indexes and original spellings.
HTTP Header Occurrence Stable Merge Append two explicit ordered HTTP field occurrence lists with source-side/index provenance, preserving Set-Cookie and all repeated values rather than comma combining.
HTTP Header Occurrence Value Redaction Redact complete supplied HTTP field values by explicit case-insensitive names without modifying occurrence order; not a guarantee that sensitive data is absent elsewhere.
HTTP Header Outer Whitespace Span Map Map leading/core/trailing HTTP optional whitespace spans, recognizing SP and HTAB only and preserving raw UTF-16 coordinates.
HTTP Header Parameter Order Formatter Format ordered HTTP parameter records with token-or-quoted-string values, preserving repeated names and order; no RFC 8187 extended-value inference.
HTTP Header Parameter Repeated Value Groups Group repeated exact decoded HTTP parameter values by case-insensitive name plus case-sensitive value, reusing the existing parameter parser.
HTTP Header Quoted Token Source Map Map complete HTTP quoted-string source spans and decoded quoted-pair values; token contents are Latin-1/HTAB and unclosed escapes/strings reject.
HTTP Header Singleton Occurrence Audit Audit repeated HTTP fields only for caller-declared singleton names; does not invent a universal singleton table or enforce request-smuggling policy.
HTTP Header Top-Level Comma Token Splitter Split HTTP comma lists with the existing quote/escape-aware scanner, not generic parentheses or CSS syntax; trims outer whitespace and preserves quoted text.
HTTP Header Value Control Character Audit Audit a supplied HTTP field value for forbidden controls or non-Latin-1 code units, retaining exact UTF-16 positions; does not repair or parse a message.
HTTP Link Header Parser Parse RFC 8288 link targets and parameters while retaining quoted delimiters and repeated relation parameters.
HTTP Method Validator Check whether a case-sensitive HTTP request method is a nonempty RFC token; custom extension methods are allowed.
HTTP Quality Exclusion Partitioner Partition explicitly supplied token quality weights into q=0 exclusions and positive candidates; validates HTTP thousandth precision, no negotiation inference.
HTTP Quality Stable Order Stable descending explicit HTTP quality ordering with original indexes and zero-quality entries retained; not full Accept specificity negotiation.
HTTP Quality Threshold Selector Select positive explicit HTTP qualities at or above a supplied unit threshold; q=0 remains excluded even at threshold zero.
HTTP Range Parser Parse exactly one RFC byte-range specifier, preserving closed, open-ended, and suffix forms without resolving it against resource length.
HTTP Set-Cookie Parser Parse one Set-Cookie field into its cookie pair and ordered attributes, preserving extensions and Expires text.
HTTP Set-Cookie Serializer Serialize one cookie pair and explicit attributes while rejecting characters that can create additional header fields.
HTTP Status Category Classify an HTTP response status code into its RFC 9110 1xx–5xx response class.
HTTP Status Message Look up a status-code description in the IANA 2025-09-15 registry snapshot, with an explicit unknown result for unassigned codes.
HTTP Token Offer Intersection Intersect explicit HTTP token offers against a case-insensitive token bank or wildcard, preserving offer order and duplicates; no language/media subtype matching.
HTTP User Agent Is Bot Calculator Bounded heuristic based on a spoofable User-Agent bot token pattern match, not reliable device/identity/automation classification or security/authentication decision. Empty string matches false, no network or parser claim.
HTTP User Agent Is Mobile Calculator Bounded heuristic based on a spoofable User-Agent mobile token pattern match, not reliable device/identity/automation classification or security/authentication decision. Empty string matches false, no network or parser claim.
