Hello gurus,
I am new to portals, AJAX and JQuery. If my teminalogy is not correct, please forgive me.
I am making AJAX call to server from JQuery datatable. On the server(portal) side, this is being served in serveResource() method.
I am pushing data in aoData in fnServerParams. When i am sending more data (more than 2000 charactes) i am getting GET 500 Internal Server Error.  This call is working fine with less data.

I think we have some 2K size limitaion in GET method. Can we switch to POST method ? If so what changes we need to do on AJAX call and portal side ? If using POST is not good solution please point me right direction ?

line 36 I see : "type": "GET",
so change it to : "type": "POST",

...and be sure to handle POST instead on server side
