CI type url is: "http://www.test.com/index.php/Uploader"
so when i acceess this url directly from browser then their is no problem but when i pass it as an action of aurigma (image uploader) it doesn't recognize it.
Thats why, i want a solution for that as image uploader has a jar file and i cant recognize its functionality, how he handle action request.
