To exclude certain URLs from being tracked, set the environment variable ``OTEL_PYTHON_FLASK_EXCLUDED_URLS`` with comma delimited regexes representing which URLs to exclude.
For example,

export OTEL_PYTHON_FLASK_EXCLUDED_URLS="client/.*/info,healthcheck"
will exclude requests such as ``https://site/client/123/info`` and ``https://site/xyz/healthcheck``.
