Problems with urlread/webread

Hi there everyone

Im using a function to download stock prices from yahoo finance. The function works well with most of the tickers but it fails sometimes. Debugging the function, I realized that the problem is localized to line 168, where it calls 'urlread'. It turns out that the URL is correct, and if I place it in a browser, I do see a CSV file with the propper data.... however, the urlead function is failing to bring that info to the workspace.

you can replicate the problem calling the following:

stocks = hist_stock_data(now-100,now,'NVDA','frequency','d');

(you can debug the function in line 168, and see how the url works fine in a webbrowser)

and, for example, it works with

stocks = hist_stock_data(now-100,now,'SPY','frequency','d')

my guess is that it should be something very simple with respect to urlread / webread. Maybe some expert can help me with this.

thanks in advance
