- Hack to stop hitting unreachable on referer
- add fetch_done to make sync work
- Make datauris work by setting the response URI, spec bug
- Allow for empty bodies
- Make request bodies work (pass to http, fix fencepost in iter count)
The current logic for a cors cache match does not consider "credentials
is false and request's credentials mode is not "include" or credentials
is true."
In function Request::fetch_main, flag local_urls_only (if set)
should allow fetching local urls only. Before this change, the flag had
the inverse behaviour.
