Saving a spreadsheet from a URL and opening it as a text file

I need to download a spreadsheet from a URL (for example http://ichart.finance.yahoo.com/table.csv?s=TSCO.L&d=0&e=19&f=2013&g=d&a=6&b=1&c=1988&ignore=.csv). I then want to open this file as a text file in my program so that I can read the historical prices of the stock. At the moment, I have saved the prices into a text file myself and am able to read from this, however this would involved me keep updating it manually myself to get the updated prices.

Any help would be much appreciated.

Thanks
