Test:
launches 147.151.240.234 and 147.151.241.151 Tomcat and puts a test.jsp file on it.
The test.jsp output on the 151 machine is the JSP in Tomcat instance 151 
test.jsp output on 234 machines The JSP in Tomcat instance 234
Access http:/ /localhost:3128/xxxweb/test.jsp will output the above results in turn.
access to a JSP is forwarded to the Web server each time: X-cache: miss from squidhost
