Question: I have a web server running on my Mac and I'd like to be notified (via Growl for example) when someone accesses my server.

I searched for something like that in Automator but found nothing.

Do you know if this is possible ?

Thank you.

Answer: 
One of the most powerful methods of getting notifications from a web server is to build in support for [webhooks](http://wiki.webhooks.org/w/page/13385124/FrontPage). The [fine folks](https://stripe.com/about) behind this software stack have a [nice blog that helps describe how this might work](https://stripe.com/blog/webhooks) if you wanted to code this into the web site.
Growl can probably do this for you automatically:
