Idhttp grab file size downloaded

Question

Well, I would like to know how to find the file size that is being downloaded with the Idhttp component.

Answer 1

You must request the HEAD operation with the file address

var
  HttpClient: TIdHttp;
  FileSize: Int64;
begin
  HttpClient := TIdHttp.Create(nil);
  try
    HttpClient.Head('http://somewhere.com/somefile.exe');
    FileSize := HttpClient.Response.ContentLength;
  finally
    HttpClient.Free;
  end;
end;
