Flask (sometimes) sends a `Set-Cookie` header for the session when serving .svg

Is there some way to tell Flask that that is not appropriate and not to do it?

You might be able to do something like flask.session.modified = False?

Thanks for the reply! As it stands most of these files are served "automatically" from the static_folder.

Our exact initialization looks like this:

class PDFlask(Flask):
    def __init__(self, import_name: str) -> None:
        shared_web_path = os.path.abspath(os.path.dirname(__file__))
        static_folder = os.path.join(shared_web_path, 'static')
        super().__init__(import_name, static_folder=static_folder)
        …

Is there a way to set flask.session.modified = False when setting from the static_folder?

I tried setting this for the favicon (where there is some explicit code rather than relying on url_for and static_folder) and it worked :)
