I know I can fetch url from AppEngine. But I just want to ping a website, without to get any other data. Is it possible?

"ping" as in ICMP or "ping" as in send an HTTP request without getting the full response? If the latter, just send a HEAD request instead of a GET.
If the former, then that probably depends on your language of choice on AppEngine
- For python, check out Ping a site in Python?
- For java, check out http://blog.taragana.com/index.php/archive/how-to-do-icmp-ping-in-java-jdk-15-and-above/

I don't want to get the full response. I just want to know that it's working. Some sites have very big index pages which is not good for my quota. – pocoa May 16 '10 at 13:22

That's exactly what a HEAD request does, it retrieves the status header for a page but not the content. – wump May 17 '10 at 09:55

There is a whitelist of modules and an FAQ about notable exclusions. You can't do it; use whaley's HEAD request.
It is also possible for an ICMP un-pingable to serve web-pages and a ICMP pingable site to do nothing but respond to pings.
