Frame Forwarding Viewport

Frame Forwarding Viewport

I have a page that have a permanent redirect to another URL and passes a parameter. It is working fine and my page is perfect in iPad, iPhones or Android devices. I am using the following meta tag:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0,user-scalable=no">

The problem is that the user perceive that he is being redirected and this avoid him to favorite the original URL for example.

To not change the URL, I have set my server to frame forward the page, instead of standard forwarding. This way I can keep the URL as original one. The major problem is that the site does not fit well the page anymore. The fonts are smaller and the text boxes are very wide.

Have you faced a problem like this one? Is there a way to say to frame content (or the parent frame, I believe) to have the same size of the device?

To demonstrate my question I have two sites that behaves differently:

http://www.heraorion.com.br --> standard forwaring
http://www.athenaapolo.com.br --> frame forwaring

Thanks in advance,
