title: can we pass null in the url parameter?
body: <p>I have a Asp.Net webApi controller as below:</p>
  
  <pre><code>[RoutePrefix("business/api/v1")]
  public class BusinessController : ApiController
  {
  
  
      [Route("GetDetails/{id}")]
      public HttpResponseMessage Get(string id)
      { 
          // get business details code.
        } 
    }
  </code></pre>
  
  <p>Is there anyway that client can hit this api with id null??</p>
