I have been playing with the v1/public server to get some stock quote data. The query I'm using is:

'http://query.yahooapis.com/v1/public/yql?q=select+symbol%2C+LastTradePriceOnly%2C+Change%2C+PercentChange%2C+MarketCapitalizinance.quotes+where+symbol+in+%28%22AAPL%22%29&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env'

I have put this into a script to have it cache the data to a file and want to update it every 5 mins or so, which should be well below the accepted rate limits.

I built this and tested it in a local environment, but when I put it up on my web server I immediately started getting the 999 error.

Anyone run into this and know what I might be doing wrong?
