Getting Hostname IDP is running on

[Christopher Bland]

Hi All,

I have setup a cluster of v3.4.4 IDP servers sitting behind a load balancer. I am looking to tag my login pages so I know which server a user hit if there’s a problem.  I have looked at Request.getServerName() and Request.getIPAddress() which are both part of HttpServletResponse.  Unfortunately because my serves are behind a load balancer when I call either method I can only see the IP address and DNS name on the load balancer and. not the actual server name.  While I am not a Java programmer,  I have been digging into possible solutions and I think I need to access the java.net.InetAddress class so I can call getLocalHost() and/or getHostName().

I am assuming that java.net.* is part of the default context.  If not is it recommended to add it?  I think I can  context.put("InetAddress",  InetAddress.class); to add InetAddress to the context.  Additionally, if java.net.* is part of the default context do I access it via context.getLocalHost()?

I welcome all suggestion and thoughts,

-Chris
