The new "smart app banners" have a method where you can pass parameters to yor app so that it can know, for examples what page on your site the user was on before they bought your app. This is useful, for example, with a news site where you ant to show them the article you were previously displaying.
The way to do this with he smart app banners is:
<meta name="apple-itunes-app" content="app-id=311507490, app-argument=http://bookID/1234"/>
Is there a way to make a general link that does this, instead of a smart app banner?
