Subject [jira] Commented: (HTTPCLIENT-656) IP address of the server of a HttpConnection
Date Thu, 12 Jun 2008 10:15:50 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12604470#action_12604470
] 

Ralf Hauser commented on HTTPCLIENT-656:
----------------------------------------

ortwin, we do know what server we are going for, but in high performance environments, a dns
may be resolved to multiple ip addresses and we would like to know which one we are currently
using since even if there is DNS round robin or alike, this doesn't mean all physical instances
of an identically named service behave the same way...

> AFAIK it's not possible to get the IP address of the server of a HttpConnection.
> I propose to add a getServerAddress() method to the HttpConnection class that returns
the IP address of the server, if the connection has been opened.
> And either returns null or throws an Exception if the IP address is not available, i.e.
the connection is not open.
> Below is a workaround for getting the IP address in current versions.
> -----------------------
> package org.apache.commons.httpclient;
> import java.io.IOException;
> import java.net.InetAddress;
> public class InetAddressFetcher {
> 	private HttpConnection hc;
> 	public InetAddressFetcher(HttpConnection hc) {
> 		this.hc = hc;
> 	}
> 	public InetAddress getInetAddress() throws IOException {
> 		if (!hc.isOpen()) {
> 			hc.open();
> 		}
> 		return hc.getSocket().getInetAddress();
> 	}
> }
