It does not open some websites. What could be the reason

This code is kind of a hack, you really aren't supposed to be able to display cross-domain or restricted content. So it's hard to say, but from my experience many websites will 1) redirect resources, 2) check domain, 3) have authentication that this logic can't handle, and so on. So for example, if the site is behind a login, this code probably just wont work. Pretty cool when it does though!
