My web app displays correctly when I use the original Amazon EC2 server URL. The page fills the whole screen as expected. However, if I access the same web app over the forwarded domain (Forward with Masking) the page is too small. I guess the app is displayed in a frame and consequently the viewport meta tags are ignored because they are inside the frame instead of in the head section.
Any tips how to correctly achieve the domain forwarding without breaking my app?
