Cancel slow-loading external scripts

Question

I am dynamically adding script tags to the DOM so I can download JSON data. Occasionally something goes wrong with a download, and the script fails to load properly.

How do I tell the browser to give up on a script that has taken too long to load? I think this is important because the browser limits the number of open requests at one time, and I don't want to waste it with dead connections.

I tried removing the script tag from the DOM, but that seems to have no effect.

I'm not sure that you can control how the browser loads a script once you've inserted it into the DOM.

However, if you use an XMLHttpRequest to download the JSON data, you can call the abort method if the request takes too long.
