Hi, Masters!

Why does facebook “https://www.messenger.com” didn’t appear on page load of HTMLViewer1 on my XOJO WEB APP?
Anybody had encounter this problem?

Apparently, that site is set to not display in an iframe. Checked it in an HTML iframe as well.

Hi Mitchel,

What do you mean " Checked it in an HTML iframe as well." ?

Where to find it?

The control that lies underneath the WebHTMLViewer is the HTML iframe element.

I checked that indeed that site cannot be displayed within an iframe, henceforth WebHTMLViewer. It is possible for web sites to prevent other sites to display them within an iframe.

That is also the case for Xojo Web apps is App.Security is set to prevent displaying the app in an iframe.

Thanks for the explanation.

Now I know.
