SCGI: combining headers with identical names (ticket #1724). SCGI specification explicitly forbids headers with duplicate names (section "3. Request Format"): "Duplicate names are not allowed in the headers". Further, provided headers are expected to follow CGI specification, which also requires to combine headers (RFC 3875, section "4.1.18. Protocol-Specific Meta-Variables"): "If multiple header fields with the same field-name are received then the server MUST rewrite them as a single value having the same semantics".
