Suppose I have a domain www.example.com and the project is hosted in  tomcat/linux/apache_server
Say  www.example.com is fetching the file from /tomcat/apache-tomcat-7.0.63/webapps/proejct_folder
Now, what I want to do is www.example.com/cms or cms.example.com to redirect to different project folder. Which is hosted in same webapss folder like 
/tomcat/apache-tomcat-7.0.63/webapps/cms_proejct_folder
How can I do that in linux? What I need to do? Any help please
