title: Find POST URL from JavaScript
body: <pre><code>https://www.artsnow.com/Login.aspx
  </code></pre>
  
  <p>I'm trying to write a script that automatically logs into my account using cURL, obtains information from my account, checks that information against a previous obtainment to see if it has changed, and if it has, text my phone as a result. Since the form submit button uses some kind of JavaScript to make the POST, I can't figure out the URL to log in.</p>
  
  <pre><code>https://www.artsnow.com/Login.aspx?
  ctl00$cphMain$chCenter$ctl01$el$UserName=my%40email.com&amp;
  ctl00$cphMain$chCenter$ctl01$el$Password=mypass&amp;
  ctl00$cphMain$chCenter$ctl01$el$LoginButton=[???]
  </code></pre>
  
  <p>After doing some research, the Javascript they are using is part of something from ASP.NET. Any ideas?</p>
