OnBrowserCheck in IW15.2.20

[jeroen.rottink]

Hi Alexandre,

I use following code to disable unsupported browsers but keep support for some apps using a rest api

Code:

// Step 1. OnBrowserCheck
procedure TIWServerController.IWServerControllerBaseBrowserCheck(
  aSession: TIWApplication; var rBrowser: TBrowser);
begin
  // REST method is often called from a non-browser. change this so the call is accepted
  if (rBrowser is TOther) and aSession.Request.PathInfo.StartsWith('/restapi/')
  then begin
    rBrowser.Free;
    // accept the unknown browser as Firefox (probably the best idea)
    rBrowser := TFireFox.Create(TFireFox.MIN_VERSION);
  end
  // handle unknown and non-supported browsers, they don't belong there (often script kiddies)
  else if not rBrowser.IsSupported
  then begin
    rBrowser.Free;  // free current browser object because it will throw an exception otherways
    rBrowser := TFireFox.Create(TFireFox.MIN_VERSION);

    TerminateSession(aSession, 403, 'Forbidden');
  end;
end;

In IW15.2.20 requesting the restapi gives a AV because aSession is nil like stated in the release notes.
Can I test the request in this function in another way?
