2. Cros - the benefits and drawbacks
What are Cro's?
Cro's, also known as cross-origin resource sharing, is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served.
A typical use case for Cro's is when a web page served from one domain, such as example.com, makes a request for a resource from another domain, such as api.example.com. The browser's same-origin policy prevents the request from being made unless the response from the other domain includes the appropriate CORS headers.
The CORS headers allow the browser to determine whether or not to allow the cross-origin request. If the headers are present and indicate that the request is allowed, then the browser will make the request. Otherwise, the browser will block the request.
The CORS headers also allow the server to specify which origin domains are allowed to make the request. This is done by specifying a list of allowed origin domains in the Access-Control-Allow-Origin header.
The Access-Control-Allow-Methods header specifies the methods that are allowed for the cross-origin request. The Access-Control-Allow-Headers header specifies the headers that are allowed in the request.
The Access-Control-Expose-Headers header specifies the headers that are allowed to be exposed to the browser.
The CORS headers are not always required. If the server does not want to allow cross-origin requests, then it can simply omit the headers. Likewise, if the server wants to allow all cross-origin requests, it can specify a wildcard in the Access-Control-Allow-Origin header.
The CORS headers are only required for cross-origin requests that use certain methods or headers. For example, a request that uses the POST method must have the Content-Type header specified. Likewise, a request that uses the Authorization header must have the Origin header specified.
The CORS headers are not required for cross-origin requests that use the GET or HEAD methods. Nor are they required for cross-origin requests that use the XMLHttpRequest or Fetch APIs.
