/**
 * This module was for the most part based on the code of cfworker's RequestBuilder
 * https://github.com/cfworker/cfworker/blob/master/packages/web/src/response-builder.ts
 *
 * The main differences:
 * - No magic static setting
 * - No magic statusText handling
 * - Removed etag, lastModified, type helpers, instead added 'set' and 'get' shorthands.
