How do I prevent visitors from opening a page outside iframe

How do I prevent visitors from opening a page outside iframe

I think the issue was by ths following , Since an iframe makes a GET request there isn't really any way to distinguish a GET request coming from the browser itself and one coming from an iframe embedded in a page. In both cases the browser makes the same GET request. You could probably write some JavaScript code in your "iframe" page that detects whether or not it is loaded in the top window and redirects if it isn't.
From the accepted answer on How to identify if a webpage is being loaded inside an iframe or directly into the browser window?
code :
<script type="text/javascript">
    if (top === self) {
        location = '/index.php';
Is there a way to prevent the download page from opening in R Shiny?

Is there a way to prevent the download page from opening in R Shiny?

like below fixes the issue Vincent's solution using two buttons, an action button for the calculation and a download button for the download is the one I went with. An additional bonus to this solution is the progress bar that also comes in the shinyIncubator package.
An explanation of my code incase someone else wants to do the same thing:
code :
actionButton("makePlots", "Calculate Results"),
      uiOutput("mytabs")) # dynamic rendering of the tabs
    output$download_button <- renderUI({
              downloadButton("downloadPlots", "Download Results")

    if(input$makePlots>counter){ # tests whether action button has been clicked


       withProgress(session, min=1, max=15, expr={ # setup progress bar

       for(i in 1:15){


         setProgress(message = 'Calculation in progress',
              detail = 'This may take a while...',

       } # end for

       }) # end progress bar

       counter<<-counter+1 # needs the <<- otherwise the value of counter
                           # is only changed within the function

       download<<-TRUE     # something to download     

     } # end if

}) # end function
output$downloadPlots <- downloadHandler(

    filename = function() { my_filename.zip },
    content = function(file){

      fname <- paste(file,"zip",sep=".") 
      zip(fname,new_directory_for_output) # zip all files in the directory

      unlink(new_directory_for_output,recursive = TRUE) # delete temp directory
      download<<-FALSE # hide download button 

    ) # end download handler

With these it helps You need to check, on every request that requires a login, that the user is logged in and is authorized.
A good way of looking at this is seeing the request URL as part of the input to your program. Just like the cookies and GET/POST parameters are input.

How to find WPF Page in navigation history to prevent opening the page again

hop of those help? Pages are rarely used in commercial apps. As I understand it, they were really intended for xbap ( wpf in a browser ). It's much more usual to have usercontrols hosted in a contentcontrol. In which case there are two commonly used alternatives
1) View First. Hold a dictionary of usercontrols keyed by type. https://gallery.technet.microsoft.com/WPF-Navigation-Basic-Sample-11f10c74
code :
    public partial class MainWindow : Window
        public MainWindow()

        private void Button_Click(object sender, RoutedEventArgs e)
            Button btn = (Button)e.OriginalSource;
            Navigate(btn.Tag as Type);

        private void Navigate (Type viewType)
            UserControl uc;
            if (Views.ContainsKey(viewType))
                uc = Views[viewType];
                uc = (UserControl)Activator.CreateInstance(viewType);
                Views[viewType] = uc;
            NavigationParent.Content = uc;
        private Dictionary<Type, UserControl> Views = new Dictionary<Type, UserControl>();
