title: ASP.NET MVC 5, return image from BLOB
body: <p>Since the domain of the BLOB is inaccessible to some devices, I have to use my Portal(ASP.NET MVC 5) to route the request. Here is the code:</p>
  
  <pre><code>public class ImageController : Controller
  {
      [HttpGet]
      public async Task&lt;HttpResponseMessage&gt; GetImage()
      {
          UriBuilder uriBuilder = new UriBuilder()
          {
              Scheme = "https",
              Host = "portalvhdszhm9fnx146yln.blob.core.windows.net",
              Path = "ads/logo.jpg"
          };
  
          using (HttpClient client = new HttpClient())
          {
              return await client.GetAsync(uriBuilder.ToString());
          }
      }
  }
  </code></pre>
  
  <p>My intent were to make the controller a router to a blob file. But the controller returns the following:</p>

  <p>What I want is to show the blob image when the controller is required. What is the correct code to do it?</p>
