All you need to do is build a Web API DelegatingHandler like this:

public class ProxyHandler : DelegatingHandler
{
  protected override async System.Threading.Tasks.Task SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)
  {
    UriBuilder forwardUri = new UriBuilder(request.RequestUri);
    //strip off the proxy port and replace with an Http port
    forwardUri.Port = 80;
    //send it on to the requested URL
    request.RequestUri = forwardUri.Uri;
    HttpClient client = new HttpClient();
    var response = await  client.SendAsync(request,HttpCompletionOption.ResponseHeadersRead);
    return response;
  }
}
