Adding a custom middleware to help with custom authentication

[semoac]

Hi!

I'm trying to enable REMOTE_USER as authentication method and I need to add a new middleware to process a header.

I did find information about using ADDITIONAL_MIDDLEWARE to add the new middleware on superset, but looks like that no longer works.

Can someone help me by find information on how to define a middleware by editing webserver_config.py? I'm kinda lost between flask appbuilder, airflow and superset.

Thanks.

I did the following to loa the xray middle ware for flask:

from flask import current_app
from aws_xray_sdk.core import xray_recorder
from aws_xray_sdk.ext.flask.middleware import XRayMiddleware

xray_recorder.configure(service='My application')
XRayMiddleware(current_app, xray_recorder)

I did load it in an Airflow plugin instead of the webserver_config.py.
