  • Access-Control-Allow-Origin: *

    Controls origins (websites) that are allowed to load data from this web service over JavaScript-based APIs as part of Cross-Origin Resource Sharing (CORS) standard.

The target server has to explicitly allow the origin domain using the Access-Control-Allow-Origin (ACAO) header, or it may allow all origins to access it using a wildcard *.
