title: How can i find which anchor has been clicked for download in destination page with out using query string
body: <p>I am having a web form initially which have href as follows</p>
  
  <pre><code>   &lt;a href="downloadInfo.aspx"&gt;ACH File Management System Trail(msi)&lt;/a&gt;
     &lt;a href="downloadInfo.aspx"&gt;ACH File Management System Trail(zip)&lt;/a&gt;
  </code></pre>
  
  <p>These are my two anchor tags when i click on this i will redirect both to a same page where user has to fill details and a mail will be send to the user for the given mail id. When the user clicks on mail i would like to have the download for  which he opted to download. If msi means i would like to prompt msi file to be downloaded and if zip it should be downloaded</p>
  
  <p>I need this to be worked with out using <strong>query-string</strong> </p>
