Way to check my server is still running?

[Cheetah Designs]

I want a way to check that my web server is still running and email me if it isn't.

How should I go about this? (I don't want to spend any money).

I was get a free hosting service and get a cron job to download a page from my web server every 15 minutes. If it can't get the page - send me an email?

Would this work? Would there be problems with caching?
