func IsValidAuthority ¶ added in v0.17.17

func IsValidAuthority(authority string) bool

IsValidAuthority reports whether authority is safe to use as an HTTP Host value for proxying and Forwarded header construction.

This is intentionally a pragmatic ASCII allowlist, not a full DNS/IP validator. It accepts hostname-like reg-names, IPv4-like values, and bracketed IPv6 literals with an optional port. Its primary purpose is to reject Forwarded header delimiters, quoting characters, whitespace, control characters, and other bytes that could change the structure of a Forwarded header.

In particular, ',' and ';' are rejected to prevent Forwarded header element/parameter injection.
