When my browser address is 127.0.0.1:8000, the address is redirected and the redirected address is
`http://127.0.0.1:8000/sso/login/?_target_path=http%3A%2F%2F127.0.0.1%3A8000%2Fotp%2Fvalidate%2F%3F_target_path%3Dhttp%253A%252F%252F127.0.0.1%253A8000%252Fotp%252Fvalidate%252F%253F_target_path%253Dhttp%25253A%25252F%25252F127.0.0.1%25253A8000%25252Fotp%25252Fvalidate%25252F%25253F_target_path%25253Dhttp%2525253A%2525252F%2525252F127.0.0.1%2525253A8000%2525252Fotp%2525252Fvalidate%2525252F%2525253F_target_path%2525253Dhttp%252525253A%252525252F%252525252F127.0.0.1%252525253A8000%252525252Fotp%252525252Fvalidate%252525252F%252525253F_target_path%252525253Dhttp%25252525253A%25252525252F%25252525252F127.0.0.1%25252525253A8000%25252525252Fotp%25252525252Fvalidate%25252525252F%25252525253F_target_path%25252525253Dhttp%2525252525253A%2525252525252F&_hash=qS1aZmPbmH86aLypRGDFH0hZVhUiOY86gHCPj0JNNEE%3D`
