Hi experts , I have finished my web application , and now I would deploy it in centos , I need to call my web application the index page like this url http://intranet it goes directly to index page . My web application including the index page is under Root directory . actually I can access my web application and the index page by using http://ipAddress and I don't want to use ip , I want the host name instead
please tell me how to change this , resolving ip address to host name called intranet

is there away to do that
