(will be removed after 0.210.0) Import from https://deno.land/std/crypto/unstable_cookie_map.ts instead.
Allows merging of various sources of headers into a final set of headers
which can be used in a Response.
Note, that unlike when passing a Response or Headers used in a
response to CookieMap or SecureCookieMap, merging
will not ensure that there are no other Set-Cookie headers from other
sources, it will simply append the various headers together.
import { mergeHeaders } from "https://deno.land/std@0.207.0/http/cookie_map.ts";
