Not an R question, but see https://addons.mozilla.org/en-US/firefox/addon/cliget/ for an easy way to see what what is going on under the hood when you download using firefox. For your example I get
wget --header='Host: www.nseindia.com' --header='User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' --header='Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' --header='Accept-Language: en-US,en;q=0.5' --header='Connection: keep-alive' 'http://www.nseindia.com/content/historical/DERIVATIVES/2014/JUL/fo09JUL2014bhav.csv.zip' -O 'fo09JUL2014bhav.csv.zip' -c Now you just need to translate that to R. (Or not, sometimes its easier to just shell out (using e.g., 'system()' ) and download with wget or curl).
