Simplest Way To Send Integers From Browser to Arduino

I have written a crude sketch to control a temperature and display the data when requested from a browser. This is what is displayed on the browser:

Time is 5:55:43
Requesting temperatures...
...
Temperature 1: 67.77
Temperature 2: 68.45
Temperature 3: 67.66
...
Current Set Point: 74

I would like to add a simple method of sending a new set point to the Arduino, something like this:

Time is 5:55:43
Requesting temperatures...
...
Temperature 1: 67.77
Temperature 2: 68.45
Temperature 3: 67.66
...
Current Set Point: 74
...
New Setpoint XX Click here to send

where I could change the XX to a new temperature and send the integer value to the Arduino.

Can anybody point me to a simple example that does not require using any additional libraries, just simple html in the Arduino sketch?

Thanks.

I found a method here:

But if you have something better let me know.
