The HTTP2-Settings header field is a connection-specific header field that includes parameters that govern the HTTP/2 connection, provided in anticipation of the server accepting the request to upgrade. [19] [20] HTTP2-Settings: token64: Obsolete RFC 7540, 9113: If-Match
The authorization method and a space character (e.g. "Basic ") is then prepended to the encoded string. For example, if the browser uses Aladdin as the username and open sesame as the password, then the field's value is the Base64 encoding of Aladdin:open sesame, or QWxhZGRpbjpvcGVuIHNlc2FtZQ==. Then the Authorization header field will appear as:
Here, service.example.com uses CORS to permit the browser to authorize www.example.com to make requests to service.example.com. If a site specifies the header "Access-Control-Allow-Credentials:true", third-party sites may be able to carry out privileged actions and retrieve sensitive information.
In computing, POST is a request method supported by HTTP used by the World Wide Web. By design, the POST request method requests that a web server accepts the data enclosed in the body of the request message, most likely for storing it. [1] It is often used when uploading a file or when submitting a completed web form.
Commonly-used header fields The following fields are commonly used in the header of a JWT typ: Token type If present, it must be set to a registered IANA Media Type. cty: Content type If nested signing or encryption is employed, it is recommended to set this to JWT; otherwise, omit this field.

There are many ways of checking whether a patch was applied successfully. For example, the 'diff' utility can be applied to the older version and newer version of a file to find the differences between them. [1] A cached PATCH response is considered stale. It can only be used for the GET and HEAD requests that may follow the PATCH request. [1]
OAuth is an authorization protocol, rather than an authentication protocol. Using OAuth on its own as an authentication method may be referred to as pseudo-authentication. [26] The following diagrams highlight the differences between using OpenID (specifically designed as an authentication protocol) and OAuth for authorization.
Digest access authentication is vulnerable to a man-in-the-middle (MITM) attack. For example, a MITM attacker could tell clients to use basic access authentication or legacy RFC2069 digest access authentication mode. To extend this further, digest access authentication provides no mechanism for clients to verify the server's identity
