title: HTTP Web Request works for other sites, but not this one. Any ideas? (VB.NET)
body: <p>I'm writing a program in VB.NET, and I'm having trouble with my httpwebrequest code.  I've used live HTTP headers for firefox to get the correct post data, but for some reason it won't login.</p>
  
  <p>The thing is, I've used identical code for another similar site (changing just the post data) and it works just fine.</p>
  
  <p>Any thoughts?  Here is my code...</p>
