Expand description

HTTPHeaderMatch describes how to select a HTTP route by matching HTTP request headers.

name is the name of the HTTP Header to be matched. Name matching MUST be case insensitive. (See https://tools.ietf.org/html/rfc7230#section-3.2).

If multiple entries specify equivalent header names, only the first entry with an equivalent name MUST be considered for a match. Subsequent entries with an equivalent header name MUST be ignored. Due to the case-insensitivity of header names, “foo” and “Foo” are considered equivalent.

When a header is repeated in an HTTP request, it is implementation-specific behavior as to how this is represented. Generally, proxies should follow the guidance from the RFC: https://www.rfc-editor.org/rfc/rfc7230.html#section-3.2.2 regarding processing a repeated header, with special handling for “Set-Cookie”.
