AcceptRanges.type
The Accept-Ranges HTTP response header is a marker used by the server to advertise its support for partial requests from the client for file downloads. The value of this field indicates the unit that can be used to define a range. By default the RFC 7233 specification supports only 2 possible values.

The Access-Control-Allow-Origin response header indicates whether the response can be shared with requesting code from the given origin.
The Access-Control-Allow-Origin response header indicates whether the response can be shared with requesting code from the given origin.
For requests without credentials, the literal value "*" can be specified as a wildcard; the value tells browsers to allow requesting code from any origin to access the resource. Attempting to use the wildcard with credentials results in an error.
null Specifies the origin "null".

The Access-Control-Max-Age response header indicates how long the results of a preflight request (that is the information contained in the Access-Control-Allow-Methods and Access-Control-Allow-Headers headers) can be cached.
The Access-Control-Max-Age response header indicates how long the results of a preflight request (that is the information contained in the Access-Control-Allow-Methods and Access-Control-Allow-Headers headers) can be cached.
Maximum number of seconds the results can be cached, as an unsigned non-negative integer. Firefox caps this at 24 hours (86400 seconds). Chromium (prior to v76) caps at 10 minutes (600 seconds). Chromium (starting in v76) caps at 2 hours (7200 seconds). The default value is 5 seconds.

The Access-Control-Request-Headers request header is used by browsers when issuing a preflight request to let the server know which HTTP headers the client might send when the actual request is made (such as with setRequestHeader()). The complementary server-side header of Access-Control-Allow-Headers will answer this browser-side header.

The Referer HTTP request header contains the absolute or partial address from which a resource has been requested.

The Referer header allows a server to identify referring pages that people are visiting from or where requested resources are being used. This data can be used for analytics, logging, optimized caching, and more.
When you click a link, the Referer contains the address of the page that includes the link. When you make resource requests to another domain, the Referer contains the address of the page that uses the requested resource.
The Referer header can contain an origin, path, and querystring, and may not contain URL fragments (i.e. #section) or username:password information. The request's referrer policy defines the data that can be included. See Referrer-Policy for more information and examples.
