I used the lastest Webserver chunked example cut out the example web page with the voltage reading and inserted a dynamic webpage; one that reads senors and real time clock. Should be a cut and paste operation... it does not load in Firefox 27 or Internet Explorer 11.
void listen(){
// listen for incoming
// an http request ends with a blank line
if (server.available()) {
char c = server.read();
Serial.write(c);
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == '\n' && currentLineIsBlank) {
// send a standard http response header
server.println("HTTP/1.1 200 OK");
server.println("Content-Type: text/html");
server.println("Connection: close"); // the connection will be closed after completion of the response
//server.println("Refresh: 5"); // refresh the page automatically every 5 sec
server.println("Transfer-Encoding: chunked");
server.println();
