I have added a variable for pin state now - so hopefully it will store and read the state from there on the next loop?
I can't test at the moment as I'm at work, but it compiles so will flash the code tonight!
//simple button GET server code to control servo and arduino pin 5
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html
//for use with W5100 based ethernet shields
//Powering a servo from the arduino usually DOES NOT WORK.
//note that the below bug fix may be required
