Help with Let's Encrypt auto renewal

[ioan]

I found a solution and so far works fine:

Code:

procedure TIWServerController.IWServerControllerBaseNewSession(aSession: TIWApplication);
var
  challengeResponse, challengeFileName: string;
begin
  [...] 
  else if ContainsText(WebApplication.Request.PathInfo, '.well-known/acme-challenge') then
  begin
    // for let's encrypt
    challengeFileName := WebApplication.ApplicationPath + 'wwwroot' + WebApplication.Request.PathInfo.Replace('/', '\');
    if TFile.Exists(challengeFileName) then
      challengeResponse := TFile.ReadAllText(challengeFileName)
    else
      challengeResponse := '';
    WebApplication.Response.WriteString(challengeResponse);
    WebApplication.Terminate;
  end;
end;

It seems that the above solution doesn't work with the latest intraweb version. If I try to request http://localhost/.well-known/acme-challenge/aa, the application never gets in IWServerControllerBaseNewSession and returns a "404 not found" error page.
