Just try the link yourself.

The page you get has a captcha. Once you complete the captcha, you're given a link to download the actual pdf (which worked for me).

For an Android user, you could start an intent that launches the browser. This would allow the user to complete the captcha himself and download the pdf.

  • but in their website we dont need to complete that captcha.It can be downloaded by just one click.Is it possible to do that in mobile application.. – YesAbhi Nov 17 '14 at 10:43
  • You're right. I can confirm the same behavior. It's most likely using the referrer of the originating web site to let this request go through. I can confirm that it's not using a cookie. http://stackoverflow.com/questions/3104647/how-to-spoof-http-referer – Stephan Branczyk Nov 17 '14 at 10:50
  • Be careful even if you can spoof the referrer, you should probably ask them the permission to do so. If they catch you doing something they don't like, they can always revoke your access to their api. In my opinion, you're likely to get their permission if your application has a low number of users and if you just politely ask them for it. Ideally, they should give you a unique key to authenticate with or a unique referrer for your own application, this way, they'll be able to track more accurately how much resources your app consumes from their services. – Stephan Branczyk Nov 17 '14 at 10:58

You have to save the cookies and use it with combination with referral link.

 wget --cookies=on --keep-session-cookies --save-cookies=cookie.txt MAIN_URL
 wget -O ./OUTPUTFILE --referer=MAIN_URL --cookies=on --load cookies=cookie.txt --keep-session-cookies
