title: Getting 404 Error in SignalR version 2.2.1
body: <p>Following is the code for the first model I created, which works fine:</p>
  
  <pre><code>registerModel=new registerModel();
  registerModel.contact=[]
  registerModel.contact.push(/* add 5 contacts */)
  socket.invoke("create", registerModel);
  </code></pre>
  
  <p>However, the following code, where I add 10 contacts instead of 5, does not work:</p>
  
  <pre><code>registerModel.contact.push(/*add 10 contacts */)
  socket.invoke("create", registerModel)
  </code></pre>
  
  <p>I get a <em>404 Not Found</em> error.</p>
  
  <p>Furthermore, if I instead add 200 contacts, it then results in <em>Long Url error</em>.</p>
