Controlling an ahk script remotely

[Fakespamhoax]

Hi,
I wanted to make a script and give it to my friend, but make it so that when I do something on my computer, it will disable the script remotely. I also don't want to install any programs or multiple scripts. I tried opening a website with Google docs, copying the entire thing, then comparing it to some text, so that when I changed the website, it would not be the same, but it was too slow and easy to mess up with keypreses and bad internet. How can I do this?
