Is any other open source web server available  other than Apache webserver for web application development?
If you simply Google "Open Source Web Server" you'll get a lot of results.

Nginx
Lighttpd
Cherokee
Savant
Tornado

Nginx is probably the best alternative.
Apart from Apache web server is there any open source web servers available for web application development? 
I am looking for a web server developing python web applications and deploy it and test it.
