The concept and directive are the same as above explained in the Apache HTTP section except for the way you add the header. Note that X-Frame-Options has been superseded by the Content Security Policys frame-ancestors directive, which allows considerably more granular control over the origins allowed to frame a site. With a few exceptions, policies mostly involve specifying server origins and script endpoints. The Content-Security-Policy (CSP) frame-ancestors directive obsoletes the X-Frame-Options header. Le Cross-origin resource sharing (CORS) ou partage des ressources entre origines multiples (en franais, moins usit) est un mcanisme qui consiste ajouter des en-ttes HTTP afin de permettre un agent utilisateur d'accder des ressources d'un serveur situ sur une autre origine que le site courant. frame-ancestors: "Hopefully", there are mistakes.

Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading resources. You can use the recommendation provided by OWASP here.It is a web filter that you can implement in your backend. Here's a simple example of a Content-Security-Policy header:. and Note that X-Frame-Options has been superseded by the Content Security Policys frame-ancestors directive, which allows considerably more granular control over the origins allowed to frame a site.

The HTTP Content-Security-Policy (CSP) form-action directive restricts the URLs which can be used as the target of form submissions from a given context. The value is a q-factor list (e.g., br, gzip;q=0.8) that indicates the priority of the encoding values.The default value identity is at the lowest priority (unless otherwise noted).. Compressing HTTP messages is one of the most important ways to improve the performance of a website. Compression is an important way to increase the performance of a Web site.

RFC 7235 defines the HTTP authentication framework, which can be used by a server to challenge a client request, and by a client to provide authentication information..
