title: IE displays or tries to download JSON when it should be doing an action
body: <p>EDIT: It appears the file jquery.unobtrusive-ajax.js is not being loaded into IE when IE runs. It is on the server and I can see it in the scrips but I can't find it in the IE scripts..</p>
  
  <p>I have searched several links and many have answers of changing the content-type to either text/plain or text/html.</p>
  
  <p>My issue is unique since it only happens on the development server with ie.</p>
  
  <p>Locally with IE and chrome is works fine. On the server with Chrome it works fine, IE it does not.</p>
  
  <p>I am returning a JSON object</p>
  
  <p>C#</p>
  
  <pre><code>return Json(new { success = true, approved = true, redirect = Url.Action("Index", "Dashboard") }, "text/html");
  </code></pre>
  
  <p>JS</p>
  
  <pre><code>function Redirect(data) {
          debugger;
          data = JSON.parse(data);
          if (data.success) {
              if (data.approved == false) {
                  //some code
              }
              else {
                  //some code
              }
          }
  </code></pre>
  
  <p>However all I get on my screen in the JSON object displayed out in plain text..</p>
  
  <p>{"success":true,"approved":true,"redirect":"/Home/Index/"}</p>
  
  <p>I am stumped as to why this is happening. I have tried to change the content type to all different kinds of versions. And this is only happening while running from the server and not locally.</p>
  
  <p>Here is also the responses.</p>
