Re: getServerName returns 'localhost'
Hello Ivan, The headers x-forwarded-for, x-forwarded-host and x-forwarded-server are typically added by Apache Httpd mod_proxy (1). It seems that you use Apache Httpd mod_proxy in front of your Tomcat, both located on the same server (this is the reason why get localhost). Your solution may be to look at the "ProxyPreserveHost On" directive in Apache configuration (2). If you use It would look like : ProxyPreserveHost On ProxyPass /mypath http://localhost:8080/mypath Hope this helps, Cyrille -- Cyrille Le Clerc clecl...@xebia.fr http://blog.xebia.fr (1) see http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#x-headers (2) see http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypreservehost On Wed, Mar 3, 2010 at 5:09 PM, vgud wrote: > > I tried to log all request headers and notice three interesting headers: > > x-forwarded-for : 10.0.0.24 > x-forwarded-host : myRealDomain.com > x-forwarded-server : my.server.ip.address > > So, tomcat(or someone else) does some forwarding and attach those headers on > request? > > If so where and how it is configured? > > > n828cl wrote: > > > >> From: André Warnier [mailto:a...@ice-sa.com] > >> Subject: Re: getServerName returns 'localhost' > >> > >> public java.lang.String 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. > >> Returns: > >> a String containing the name of the server > >> > >> That does not seem to work in his case. > >> > >> Does it only work when the or tags with the > >> corresponding names are set ? > > > > The code shows that the HOST header is being used by getServerName(). > > Testing with the RequestDumperFilter enabled in examples/WEB-INF/web.xml > > shows that it works as documented; here's a portion of the output from > > Tomcat running on my desktop with the default name of localhost: > > serverName=usrv-caldarcr.na.uis.unisys.com > > serverPort=8080 > > > > It appears the OP has something else going on that's interfering with the > > target IP address.

RE: getServerName returns 'localhost'
I tried to log all request headers and notice three interesting headers: x-forwarded-for : 10.0.0.24 x-forwarded-host : myRealDomain.com x-forwarded-server : my.server.ip.address So, tomcat(or someone else) does some forwarding and attach those headers on request? If so where and how it is configured? n828cl wrote: > >> From: André Warnier [mailto:a...@ice-sa.com] >> Subject: Re: getServerName returns 'localhost' >> >> public java.lang.String 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. >> Returns: >> a String containing the name of the server >> >> That does not seem to work in his case. >> >> Does it only work when the or tags with the >> corresponding names are set ? > > The code shows that the HOST header is being used by getServerName(). > Testing with the RequestDumperFilter enabled in examples/WEB-INF/web.xml > shows that it works as documented; here's a portion of the output from > Tomcat running on my desktop with the default name of localhost: > serverName=usrv-caldarcr.na.uis.unisys.com > serverPort=8080 > > It appears the OP has something else going on that's interfering with the > target IP address.

The code shows that the HOST header is being used by getServerName(). Testing with the RequestDumperFilter enabled in examples/WEB-INF/web.xml shows that it works as documented; here's a portion of the output from Tomcat running on my desktop with the default name of localhost: serverName=usrv-caldarcr.na.uis.unisys.com serverPort=8080 It appears the OP has something else going on that's interfering with the target IP address.

Re: getServerName returns 'localhost'
1. What, exactly, version of 5.5.x is used. 2. Is Tomcat running standalone, or is behind Apache HTTPD, IIS or other web server, or a load balancer 3. What connectors are configured in server.xml? What connectors (protocols) are mentioned in catalina.log at startup time. E.g.: 03.02.2010 12:10:01 org.apache.coyote.http11.Http11BaseProtocol init 4. Whether Tomcat-Native (tcnative-1.dll, tcnative-1.so) is used? 5. Operating system. 6. Are the clients using HTTP/1.1 or HTTP/1.0 Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Only if you added all possible domain names and variations thereof that get to that system's IP address(es).

More precisely :
getRemoteAddr

Returns the Internet Protocol (IP) address of the client or last proxy
that sent the request. For HTTP servlets, same as the value of the CGI
variable REMOTE_ADDR.
Andre, you're answering the question of "which client sent this request?"
The OP is asking a different question: "What hostname did the client
send this request to?"
I'd parse the host header in the request to find out, but that's just me!
You are right, I am off-base here, apologies.
String hostname = request.getHeader("Host") should work.
But then, the question is, according to the OP, request.getServerName()
returns "localhost", although that is very unlikely to have been used by
the client in the Host header.
However, the java API says :
ServletRequest.getServerName
public java.lang.String 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.
Returns:
a String containing the name of the server
That does not seem to work in his case.
Does it only work when the or tags with the corresponding
names are set ?
(A question for people who like to scan the code.. Christopher ?)

Did you do something like this in server.xml? And your client goes to www.example.com, but you getServerName() returns "localhost" in stead of "www.example.com"? Ronald.
