The code that checks for what link was requested sees the "Referer" line in the header and, for example, if an off was previously requested, the LED is toggled ON, then immediately OFF for the same request.

The easy fix is to check for the GET request (in all the similar lines):

                    if (header.indexOf("GET /?LED0=ON") != -1)
