How about some server side pushing, using something similare to the
following simple NPH CGI program written in Perl:
$| = 1; #set STDOUT to be unbuffered
binmode(STDOUT); #for windows platforms to stop adding of \r
my $boundary = '-----my-boundary-example-'.rand.'-----';
print "HTTP/1.0 200 OK\r
Status: 200 OK\r
Server: Server-Side Push Demo\r
Content-type: multipart/x-mixed-replace; boundary=$boundary\r\n\r\n";
my $time = `/bin/date`;
print "Content-type: text/html\r\n\r\n";
print "<HTML><HEAD><TITLE>Server-Side Push Example</TITLE></HEAD>\n";
print "<BODY><CENTER><H1>Server-Side Push Example</H1></CENTER>\n";
print "<H4>The time is: $time</H4>\n";
