Aren't host and/or http_host going to get you the server name?

I use this with very good results.

    public static String remoteAddress(WORequest request) {
        String remoteAddress = 
(String)request.headerForKey("x-webobjects-remote-addr");
        remoteAddress = (remoteAddress == null ?  
(String)request.headerForKey("http_pc_remote_addr") : remoteAddress);
        remoteAddress = (remoteAddress == null ? 
(String)request.headerForKey("pc-remote-addr") : remoteAddress);
        return (remoteAddress == null ? 
(String)request.headerForKey("remote_addr") : remoteAddress);
    }
