<DD>Sets the originating host name or IP address (as a String) from where the <code>Subject</code> is initiating the
<code>Session</code>.
<p/>
In web-based systems, this host can be inferred from the incoming request, e.g.
<code>javax.servlet.ServletRequest#getRemoteAddr()</code> or <code>javax.servlet.ServletRequest#getRemoteHost()</code>
methods, or in socket-based systems, it can be obtained via inspecting the socket
initiator's host IP.
<p/>
Most secure environments <em>should</em> specify a valid, non-<code>null</code> <code>host</code>, since knowing the
<code>host</code> allows for more flexibility when securing a system: by requiring an host, access control policies
can also ensure access is restricted to specific client <em>locations</em> in addition to <code>Subject</code>
principals, if so desired.
<p/>
<b>Caveat</b> - if clients to your system are on a
public network (as would be the case for a public web site), odds are high the clients can be
behind a NAT (Network Address Translation) router or HTTP proxy server. If so, all clients
accessing your system behind that router or proxy will have the same originating host.
If your system is configured to allow only one session per host, then the next request from a
different NAT or proxy client will fail and access will be denied for that client. Just be
aware that host-based security policies are best utilized in LAN or private WAN environments
when you can be ensure clients will not share IPs or be behind such NAT routers or
proxy servers.
