Current implementation is using Flask events to handle requests at the beggining and end of processing.

The alternative solution is to make it a Flask extension that adds itself as middleware wrapper around Flask application and process requests and responses outside flask context.

Advantages are:

• No interaction with flask means less complexity
• Logging of the requests as werkzeug does is not so effective inside Flask. after_request which holds the response object is not executed on exception and log event of errors may be lost
• Probably the log of requests, does not need to be repeated and a simple filter and formatter on the logger of werkzeug is enought to fix the problem

Dissadvantages:

• Need to rewrite current implementation
