[99s-extend] Cowboy unexpectedly timing out when reading the body

[Loïc Hoguin]

Yep, only once. All functions that return {ok, ...} are like this. 
There's no right approach, that's left as an exercise to the developer. :-)

You can probably use cowboy_req:set_meta/meta if you really need to pass 
it around.
