SessionState

  • Can be persisted in memory, which makes it a fast solution. Which means state cannot be shared in the Web Farm/Web Garden.
  • Can be persisted in a Database, useful for Web Farms / Web Gardens.
  • Is Cleared when the session dies - usually after 20min of inactivity.

ViewState

  • Is sent back and forth between the server and client, taking up bandwidth.
  • Has no expiration date.
  • Is useful in a Web Farm / Web Garden
