title: problem with VB.net WebRequest return page with no results
body: <p>I am trying to get the html response of a Kayak.com query using a <code>WebRequest</code> object, however more often that not the site returns no results, i just get an empty Kayak page, i have to try the request around 5 times before i get a result back...What can be the cause of this? My code is given below...Thanks for the input! Fernando</p>
  
  <pre><code>Dim WReq As WebRequest = WebRequest.Create("http://www.kayak.com/flights/MIA-LAX/2011-01-29/2011-02-11")
  WReq.Timeout = 100000
  
  Dim wResp As WebResponse = WReq.GetResponse()
  Dim r As StreamReader = New StreamReader(wResp.GetResponseStream(), Encoding.ASCII)
  </code></pre>
