title: using Web Api GET method
body: <p>My WEB API has a single GET method as mentioned below which will return a resource based on the id.</p>
  
  <pre><code>public HttpResponseMessage Get(string id)
  {
     ....      
  }
  </code></pre>
  
  <p>I also have a requirement wherein I need to check 
  whether a resource exists or not(no need to return resource).</p>
  
  <p>I would like to know , whether as per the true RESTful service
  do I need to write a separate GET for second requirement or use the
  existing one.</p>
