HTTP Request/Response headers should be multidict #87

Closed chiwanpark closed 2 years ago

Currently, all headers in request and response is dict. However, it should be multidict because there can be multiple items with the same key in HTTP headers. (i.e. multiple Set-Cookie headers to store multiple cookies)

The werkzeug implementation is based on custom implemented multidict.

Hi,

There might be a better option than multi-dict. https://github.com/Ousret/kiss-headers
