From an Angular 8 client I want to read a file located at: C:\inetpub\wwwroot
IIS is running. 
I used the following code and got this error:

Access to XMLHttpRequest at '<http://localhost/MyFile.xml>' from origin '<http://localhost:4200>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

In IIS configuration I added: Access-Control-Allow-Origin, \* to:
HTTP Response Headers. 

But I got the above error also when IIS was stopped. 

Can you please explain what is wrong ?

Thank you in advance,
Zvika 

```
let headers = new HttpHeaders;
headers.append ('Access-Control-Allow-Origin','*');
this.http.get ('http://localhost:80/dwell.xml',{headers: 
headers}).subscribe(
  (val) => {
      console.log("GET call successful value returned in body", 
                  val);
  },
  response => {
      console.log("GET call in error", response);
  },
  () => {
      console.log("The GET observable is now completed.");
  });

```
