title: Is it possible to automate postback from the client side?
body: <p>One of my clients needs to pull customer data from a web service periodically. The data itself is provided as CSV files via javascript postbacks, as is most of the navigation within the service's website. </p>
  
  <p>Right now, the worst bottleneck in the entire system is the need for a human to log into the web page, navigate to the download page, and manually add the downloaded file to the rest of the system. </p>
  
  <p>Can the process of downloading files via postback be automated? (Say for example via a shell script that can be run via cron?)</p>
  
  <p>If so, what would you recommend as the most appropriate tool for doing so?</p>
