curl "http://finance.yahoo.com/d/quotes.csv?s=goog&f=nsl1l2op&e=.csv" <head><title>redirect</title></head> <body bgcolor="white" fgcolor="black"> <font face="helvetica,arial"><b>  "<em>http://download.finance.yahoo.com/d/quotes.csv?s=goog&f=nsl1l2op&e=.csv</em>".<p></b></font>  <!-- default "redirect" response (301) --> </body>
