async def update_session(request):
ses = session.load_from_request(request)
ses['var'] = 'value'
response = ResponseHTML('Session has been updated')
session.save_to_response(ses, response)
return res
@app.route('/load')
async def load_session(request):
ses = session.load_from_request(request)

session = Session()
session.init(app, secret_key='REALLY_SECRET_KEY_FOR_SIGN_YOUR_SESSIONS', auto_manage=True)
