Server-Side Processing: Send Request via JSON

Using this example:
http://datatables.net/release-datatables/examples/data_sources/server_side.html

When I click the Next button on the table, the request header looks like this:

GET /release-datatables/examples/server_side/scripts/server_processing.php?sEcho=3&iColumns=5&sColumns=&iDisplayStart=20&iDisplayLength=10&mDataProp_0=0&mDataProp_1=1&mDataProp_2=2&mDataProp_3=3&mDataProp_4=4&sSearch=&bRegex=false&sSearch_0=&bRegex_0=false&bSearchable_0=true&sSearch_1=&bRegex_1=false&bSearchable_1=true&sSearch_2=&bRegex_2=false&bSearchable_2=true&sSearch_3=&bRegex_3=false&bSearchable_3=true&sSearch_4=&bRegex_4=false&bSearchable_4=true&iSortCol_0=0&sSortDir_0=asc&iSortingCols=1&bSortable_0=true&bSortable_1=true&bSortable_2=true&bSortable_3=true&bSortable_4=true&_=1353960845704 HTTP/1.1

My question is this: Is there any way built into dataTables that allows me to send this data via JSON instead of in the URL string? Something like:

{
   "sEcho": "3",
   "iColumns": "5",
   "iDisplayStart": 20 // etc.
}
