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. By default, a web browser will refuse to load data over XmlHttpRequest
from a website that is not in the same origin, which is a precaution against various types of data stealing attacks. 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 *
. The latter however creates a potential security issue if the website in question is transactional and processing sensitive data, so the wildcard should be only used on websites consciously offering public APIs.
The header sets permissive AJAX access by using wildcard origin *
. It may be OK if the website is a publicly accessible REST API but otherwise it should be not present at all
