title: specifying multipe method parameters in web api2 attribute routing
body: <p>I am converting some of my services to Web API2 and I have some functions which take 2 or 3 parameters. How are those routing attributes constructed?</p>
  
  <p>When I call the function from the old service in javascript its </p>
  
  <pre><code>data: { "symboltype": symboltype, "symbol": symb, "requestDate": dDate}
  </code></pre>
  
  <p>I've tried the following routing attribute among other variations, which dont work</p>
  
  <pre><code>    &lt;HttpGet()&gt; _
      &lt;Route("getsinglerangeprojection/{symboltype:int,symbol,requestdate}")&gt; _
      Public Function GetSingleRangeProjection(ByVal symboltype As Integer,
                                               ByVal symbol As String,
                                               ByVal requestDate As String) As ProjectedRange
          ...code here
      End Function
  </code></pre>
