function _backdrop_set_preferred_header_name

Sets the preferred name for the HTTP header.

Header names are case-insensitive, but for maximum compatibility they should follow "common form" (see RFC 2617, section 4.2).

Parameters

string $name: Optional. A header name with the preferred capitalization, e.g. Cache-Control or Content-Type.

Return value

string[]: The array of all current preferred header names. Keyed by a lower-case string of each header name.
