title: on html.actionlink click go to previous page
body: <p>Currently in a link </p>
  
  <p><code>Customer/businessunit/RepresentativeDetails?RepresentativeId=cd3a7263-78f7-41bd-9eb0-12b30bc1059a</code></p>
  
  <p>I have following code for view</p>
  
  <pre><code>@Html.ActionLink("Back to List", "Index")
  </code></pre>
  
  <p>which takes me to this link</p>
  
  <pre><code>customer/businessunit/index
  </code></pre>
  
  <p>but rather that going to index page I want to go to previous page when the actionlink is clicked, which is</p>
  
  <pre><code>Customer/businessunit/BusinessUnitDetails/c4a86253-a287-441e-b83d-71fbb6a588bc
  </code></pre>
  
  <p>How do I create an actionlink that directs me to previous page?
  something like <code>@Html.ActionLink("Back to Details", //go to previous page)</code></p>
