title: How to download files from file hosting services like Rapidshare.com, DepositFiles.com
body: <p>I'm looking to build a downloader application that downloads files from file-hosting services. 
  What are the steps necessary to satisfy this requirement? E.g. user adds the shared file URL and download manager should transfer the file to a local folder.
  Can there be any generic approach for all common file sharing websites or each site has a different download procedure?</p>
