how to scale to mobile device given only a url

i have a weblink from an external site. All i have is this link, it looks something like this: http://ift.tt/1FYMkva

the site is not mobile yet so it does not scale to mobile device. Remember this site is not mine and all i have is a link. How can i add something to the link so that it scales on a mobile device. For example could i add javascript to the link itself (which might not be safe to avoid injection etc).Please advise and the link is being executed from a iphone app on iOS 8.

UPDATE: Since im invoking the url from withint ios is there a command i can use that while its opening to run javascript or inject javascript ?
