title: Why is ViewState not stored on the server by default?
body: <p>Can someone give me a good reason why ViewState isn't stored on the server by default?</p>
  
  <p>Why not send a small session token in place of ViewState, which can then be mapped to whatever ViewState info is needed on the server, to prevent the whole ViewState being posted back and forwards multiple times.</p>
  
  <p>Am I missing something?</p>
