how to pass variable status from Arduino web server to mobile client?

I'd like to have my webserving arduino update a mobile site when a status variable changes in a program running on the arduino. I'm using a simple mobile site setup from Wix's mobile site developer, which right now is just three buttons which send a different command to the webserver (like http://209:135:17:45:80/?2 - not real ip address). Any guidance on if this is possible and how I might go about this? Thanks!

Generally speaking, servers do not make connections on their own to other sites. They wait for a client to make a connection request before they do any external communication. That being said, an arduino can both act as a server and client at the same time if needed. The moble site will need to be a server to receive any unrequested data from the arduino.
