title: Post and redirect FROM Web Api
body: <p><strong>Warning:</strong><br>
  This question is NOT about How to post TO a Web Api, is How to post FROM Web Api.</p>
  
  <h2>Scenario:</h2>
  
  <p>My question is related to the comments of the answer of Darin Dimitrov in:
  <a href="https://stackoverflow.com/questions/17347625/how-to-redirect-in-aspnet-web-api">How to Redirect in ASPNET Web API</a></p>
  
  <p>and is seems to be a duplicated for: <a href="https://stackoverflow.com/questions/6062078/response-redirect-which-posts-data-to-another-url-in-asp-net/6062248#6062248">Response.Redirect which POSTs data to another URL in ASP.NET</a>
  but take in consideration that the question is already old (2008) and I'm looking for answer that maybe WebApi is up to date.</p>
  
  <blockquote>
    <p>Using Visual Studio 2012 Web Api 2.1</p>
  </blockquote>
  
  <p>I've get from data in my application (is a web api) trough a POST method in a controller. So far so good. Now I want to post this data (with some changes) to an external site that accepts my data (this is validated and works).</p>
  
  <p>For this process I've tried two methods:</p>
  
  <ol>
  <li><p>Make a string with a basic form that submit with a "onload" event with javascript.<br>
  From (<a href="https://stackoverflow.com/questions/6062078/response-redirect-which-posts-data-to-another-url-in-asp-net/6062248#6062248">Response.Redirect which POSTs data to another URL in ASP.NET</a>). This is working, and this is how I'm using it, but maybe can be replaced with some better approach. </p></li>
  <li><p>With an <code>HTTPClient</code> using <code>client.PostAsync</code> . I could also work with this, but I don't want show the response to the user, I want to redirect him. Maybe can be this adapted to make a redirect?</p></li>
  </ol>
  
  <h2>Question:</h2>
  
  <p>How do I redirect sending Post variables without using the "onload" workaround or adapting the "HttpClient" to make a post-redirection without waiting for response ?</p>
  
  <p>Consideration: I don't post any code because implementations of my two options are already easy and I don't have any trouble with them.</p>
