Allow passing custom headers to metadata request in authorize_redirect by AlexandrosMaragkakis · Pull Request #710 · authlib/authlib

This pull request implements a feature to allow custom HTTP headers to be passed to the metadata request made by authorize_redirect().

Previously (#633), when calling authorize_redirect(redirect_uri, headers=headers), the custom headers were not forwarded to the GET request for server metadata, causing a 401 Unauthorized error when the endpoint was protected by a security gateway.
