<em>Note</em>: To avoid hitting the limit on the count of simultaneous
connections to the same host, imposed by the
<a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1.4">HTTP specification</a>,
the second chat window should be opened using a different URL, e.g. with
an IP address instead of the host name.
