I have been working through MIke G's tutorial, and had gotten as far as making the LED turn on and off from a web page. It had been working fine, but this morning stopped working. After rechecking things, I thought to clear the browser cache, and that got it working again - exactly once. I can click once to turn the LED on, then click the off button and it turns off, and then nothing happens again until I clear the cache again. I've tried it several times, and this is now reliably how it works.
Obviously I'm not going to be able to work through the rest of the tutorial this way. Is there a way to get the browser to NOT cache the page, so it retrieves it fresh each time and the examples actually work? I'm using Firefox 3.6.24 currently, and ideally will be able to continue to do so.
