How it works
Split commas/semicolons outside quotes, reject repeated parameter names and read for/by node identifiers.
The example has two proxy elements, including a quoted IPv6 address with port 4711.
Limits
No network access or proxy trust evaluation. Header text alone does not establish client identity. Values remain in received order; extensions are retained without applying application policy.
