Thanks for the quick reply zoomkat!! I just tried clicking "http://192.168.0.31/?b=1" in your post and it "pulses" on every 5 second refresh. I also tried...
client.println(F("<META HTTP-EQUIV=REFRESH CONTENT=5 URL=192.168.0.31>"));
and
client.println(F("<META HTTP-EQUIV=REFRESH CONTENT=5 URL=http://192.168.0.31/>"));
But it didn't change the behavior. I'm not sure I am doing what you suggested.
