"""Construct a werkzeug Response.
Responses are transmitted to the browser with compression if: a) the browser
supports it; b) it's sane to compress the content_type in question; and c)
the content isn't already compressed, as indicated by the content_encoding
parameter.
Browser and proxy caching is completely disabled by default. If the expires
parameter is greater than zero then the response will be able to be cached by
the browser for that many seconds; however, proxies are still forbidden from
caching so that developers can bypass the cache with Ctrl+Shift+R.
For textual content that isn't JSON, the encoding parameter is used as the
transmission charset which is automatically appended to the Content-Type
header. That is unless of course the content_type parameter contains a
charset parameter. If the two disagree, the characters in content will be
transcoded to the latter.
If content_type declares a JSON media type, then content MAY be a dict, list,
tuple, or set, in which case this function has an implicit composition with
json_util.Cleanse and json.dumps. The encoding parameter is used to decode
byte strings within the JSON object; therefore transmitting binary data
within JSON is not permitted. JSON is transmitted as ASCII unless the
content_type parameter explicitly defines a charset parameter, in which case
the serialized JSON bytes will use that instead of escape sequences.
Args:
request: A werkzeug Request object. Used mostly to check the
Accept-Encoding header.
content: Payload data as byte string, unicode string, or maybe JSON.
content_type: Media type and optionally an output charset.
code: Numeric HTTP status code to use.
expires: Second duration for browser caching.
content_encoding: Encoding if content is already encoded, e.g. 'gzip'.
encoding: Input charset if content parameter has byte strings.
Returns:
A werkzeug Response object (a WSGI application).
