Script being called

[duniyadnd]

Is there a way for a CGI Script to be called every 30 minutes? Even when the page is not being accessed? For instance, if I want to update a page with information to a list of articles another site has, and have to grab the necessary links, and I have to do this every 30 minutes, how would I call that?

The above is just a hypothetical example, basically no code.

Thanks

Cron can do that.

Or if you don't have cron.. fake it:
