About Question enthuware.jwpv6.2.1069 :

[himaiMinh]

for someserver.com, should it be request.getServerName() ?


It seems to me that :
1. the client is running at 10.10.2.23 using port number 2260.
2 .the client sends the request to the servlet at someserver.com and the receiving port is 8080.

No, as per http://docs.oracle.com/javaee/6/api/jav ... ServerName():
getServerName returns the host name of the server to which the request was sent. It is the value of the part before ":" in the Host header value, if any, or the resolved server name, or the server IP address.

I assume the url in the question is :
http://www.someserver.com:8080/MyContext/index.jsp.
The client is at 10.10.2.23:2262?

So, to return http://www.someserver, it should be getServerName ?

It is just like http://localhost:8080/MyContext/index.jsp.
And the localhost is to where the request is sent.

No, the problem statement says that the request is coming FROM someserver.com.
