Simple (Or not so simple) Node.js Redis Client

I love node.js. For some reason I am fascinated by V8 javascript engine and its performance. I am also a big fan of Event driven I/O frameworks like twisted or EventMachine, Javascript and nosql databases of which redis is one of the stars. For those who are not familiar with terminology Google them :).

Here is a small redis client I wrote in node.js. All it can do is to see if a key can exist or not :).
