title: How to add extra HTTP variables dynamically in jQuery datatables?
body: <p>I am using jQuery datatables for showing search results. I have some checkboxes which are used to filter results. That means, I have to send extra HTTP get variables to the server when the checkboxes are checked. How do I do that dynamically? </p>
  
  <p>I am aware that extra HTTP variables can be added using <code>fnServerParams</code>, but it can be added only at the time of init of the datatable. </p>
  
  <p>How do I add/remove HTTP variables on the event of checking/unchecking a checkbox?</p>
