I have used code From Ajax . They using same HTML syntax for there code developemnt.
I don't understand why it wont work.

client.println(F("<META HTTP-EQUIV=REFRESH CONTENT=5 URL=>"));
used instead 
client.println("<META HTTP-EQUIV=REFRESH CONTENT=5 URL=>");

In arduino forum mentioned that it print single Byte.instead of whole word.

 client.println("</form>");
                    client.println("</body>");
                    client.println("</html>");
