Python Flask mod-wsgi Custom Headers not in Request

Well this one took me many hours...

Turns out that only alphanumeric characters or '-' are allowed.

Any headers not conforming these will be ignored.

The solution is to set the claim prefix to something without _ like

OIDCClaimPrefix OIDC-CLAIM-

python apache flask mod-wsgi

Ensure your Apache configuration has the WSGIPassAuthorization directive set to 'On' so your headers get past Apache + WSGI and to your Flask app.
