useServerSession

This Boolean property is used to decide if the spell-check engine will use the IIS Session object to accelerate the dialog for each user.  Using the session will reduce the bandwidth used by the spellcheck window, but will use more server memory.

The default value is true.

Example:

var oSpell = new JavaScriptSpellCheck();
   //If you don't want your spellchecker to use the session
      oSpell.useServerSession = false
