5. Virtual directory:
* File Location:%tomcat%/conf/server.xml
* Configuration Content
<context path= "/xxx" docbase= "F:\workspaces\20120909\day04\WebRoot"/>
* Path: Browser access paths
* DocBase: The actual folder location of the current path mapping
* Note: Specify to a Web project
* Purpose: Extend the WebApps Directory management project

6. Virtual Hosting
* Local domain name effective cause localhost
* C:\WINDOWS\system32\drivers\etc\hosts
