I'm writing an ISAPI DLL, using Delphi 10.4.2 and IIS 10.

The configuration, the content, request-response, the debugging, all working fine.

But, I can't read the request 's custom Headers. The test request has come from Postman.

In `TWebModule1.WebModule1DefaultHandlerAction`, the request is inherited from `Web.Win.IsapiHTTP.TISAPIRequest`.

I'm using the `Web.Win.IsapiHTTP.TISAPIRequest.GetFieldByName()` method, as mentioned in the Embarcadero documentation.

I've added `<add name="Access-Control-Allow-Origin" value="*" />`  to the configuration file on the server side.

I feel that I'm missing something.

For example, this returns with empty content, but from the client-side I sent it, every GetFieldByName returns with an empty string.

```
TWebModule1.WebModule1DefaultHandlerAction..
begin
  Response.statuscode := 200;
  response.Content := Request.GetFieldByName('ic_Something');
  Handled := true;
 end;

```
