Code Issues Releases Activity

Introduce new type of client storage

Browse Source 
- This addresses the problem of having to update multiple times during
  one request. It's hard to have a nice interface especially with JWT
  because you always end up having to decode the request, encode new
  response, write header, then a second write to it comes, and where do
  you grab the value from? Often you don't have access to the response
  as a "read" structure. So we store it as events instead, and play
  those events against the original data right before the response is
  written to set the headers.
