title: how to submit datetime parameter to a WCF REST service
body: <p>I have a WCF Data service operation :</p>
  
  <pre><code>[WebGet]
  public bool isContractUpToDate(string contractId, string lastmodifiedDate);
  </code></pre>
  
  <p>but I don't know how to call this service from a .NET client application and how I can call this operation from Internet Explorer.
  I'm looking for some examples.</p>
