Setup ALM application url as http://alm

In one of the previous organizations I worked with, if anyone enters "http://alm" in the InternetExplorer browser the ALM application would launch.

Our current url to ALM 11 application is http://<ipaddress>/qcbin/start_a.jsp. How do I setup the shortcut url http://alm ?

Note : I am using JBoss and Apache 2.2 webserver. The environment is Linux.
