/**
|
|
* Set of standard comma-separate HTTP headers that may span lines.
|
|
*
|
|
* These headers may specified on multiple lines, e.g.
|
|
*
|
|
* Allow: GET
|
|
* Allow: POST
|
|
*
|
|
* Is the same as:
|
|
*
|
|
* Allow: GET, POST
|
|
*
|
|
* Standard headers that aren't part of this set will be overwritten in
|
|
* the event that they're specified multiple times. For example,
|
|
*
|
|
* Content-Type: application/octet-stream
|
|
* Content-Type: text/plain; charset=utf-8
|
|
*
|
|
* Is the same as:
|
|
*
|
|
* Content-Type: text/plain; charset=utf-8
|
|
*
|
|
* This set exists to optimize header lookups and parsing. The existence
|
|
* of standard headers that aren't in this set is an O(1) operation. The
|
|
* repeatable headers in this list require an O(1) operation if they are
|
|
* not present, otherwise the extended headers list needs to be crawled.
|
|
*
|
|
* Please note non-standard headers exist, e.g. Cookie, that may span
|
|
* multiple lines, even though they're not comma-delimited. For those
|
|
* headers we simply don't add them to the perfect hash table.
|
|
*
|
|
* @note we choose to not recognize this grammar for kHttpConnection
|
|
* @note `grep '[A-Z][a-z]*".*":"' rfc2616`
|
|
* @note `grep ':.*#' rfc2616`
|
|
* @see RFC7230 § 4.2
