Redirection and the Back button ??

[CastleSoft]

Hi,

 

I have a form that allows some selection then redirects to an external form using:

 

   url:= Urls[uniComboBox1.ItemIndex];

   UniSession.AddJS('window.location = ''' + url + ''';');

 

If the user is on the external form and selects the back button..

 

You get a BLANK screen on the UniGui form.

 

Can I trap this and force them back to the same state as if they freshly visited the URL ?

 

Thanks

Andrew
