title: How to add multiple headers with ok Http
body: <p>I am using Retrofit 2 and Okhttp for my android project. I want to add multiple headers in the api request.</p>
  
  <p>This is my interceptor code :</p>
  
  <pre><code>public class NetworkInterceptors implements Interceptor {
  @Override
  public Response intercept(Interceptor.Chain chain) throws IOException {
  
      Request request = chain.request().newBuilder()
              .addHeader("Userid", "10034")
              .addHeader("Securitykey", "Fb47Gi")
              .build();
      return chain.proceed(request);
      }
  }
  </code></pre>
  
  <p>This is not working properly. In server side I am getting only the last added header (in the above example I am getting only Securitykey missing "Userid" )</p>
  
  <p>Please Help.</p>
