Embedding script with timeout in case server goes down

Question

I am looking for a way to make sure an external script file won't block the viewed page,
if the server which serves it is "down" (for example port 80 is blocked for some reason).

Currently when I test by taking down the server (Apache) manually, or block that file via server's firewall, I see the browser is trying to load the resource (script in that case), without success for long period of time, until it aborts.

Is there a way to get past this issue?

my script is already at the bottom, and already is async. I need a way to make sure it won't even try to load it more than X timeout. — vsync, Jun 06 '10 at 13:31
Oh, now I understand: you want to shorten the timeout of script downloading? — Marcel Korpel, Jun 06 '10 at 13:36

Perhaps it's time to start using jQuery?

Check out jQuery.ajax() info and search for timeout keyword.

UPDATE:

For this particular solution you could use getScript() to fetch and execute remote scripts.

This isn't the same thing, the javascript file itself is timing out, jQuery won't do anything to solve this. – Nick Craver Jun 06 '10 at 13:07
Why that? In the similar manner one could load a script and execute it locally. – Andrejs Cainikovs Jun 06 '10 at 13:26
well, this requires me to tell the website which installs my script, to also install jQuery. – vsync Jun 06 '10 at 14:30
...or you could load it from your script :-) http://www.codehouse.com/javascript/articles/external/ – Andrejs Cainikovs Jun 06 '10 at 14:56
