If you are using HTTP then clients will politely tell you which DNS name
they are tryning to connect to using the "host:" header.
TCP does not give any info about "hostnames", but only about "IP Addresses"
I think .getLocalAddress().getHostName() will simply try to resolve back
the IP address to a DNS name
I hope that helps

Hi Mark,
I'm very sorry I know this is not related to the Tomcat project. However, I
cannot find anyone who I think has more expertise in java networking
programming than you.
I have a java server socket problem and I have no way to find the answer. I'm
really hoping I can get some insights from you. Thanks in advance.
And here's the URL to this question:
http://stackoverflow.com/questions/16751062/java-server-socket-binding-multiple-domain-host-names
I have a java nio server with ip address 192.168.0.1 listening on port 80. I
configured this server to bind to multiple domain/host names, let's say
server1, server2, server3 are all resolved as 192.168.0.1.
Now I'm hoping if the client connects to server1, on the server side, I can
recognize that the client is connecting to server1 instead of other names or
direct ip address, so that I can do something special, and if the client is
connecting to server2, I can recognize that the client is requesting server2,
so I can do something else special, and so on.
Now the question is: seems on the server side, I cannot easily get the correct
information which server name my clients are connecting to.
I have the follow code:
ServerSocketChannel ssChannel = (ServerSocketChannel) selKey.channel();
String boundHost = sChannel.socket().getLocalAddress().getHostName();
But it does not work, the boundHost is always the server1 even if clients
connect to server2 or server3.
Thanks,
Elgs
