In need of a simple web server

I was hacking away on an AJAX application and needed to do some XMLHttpRequest goodness. Needless to say, working with the file:// protocol has become very restrictive lately so I was in a need of a simple web server - this meant no configuration, no support, no hassle whatsoever:

$ python -m SimpleHTTPServer &

and your working directory is now accessible over at http://localhost:8000/
