facing Url problem with codeigniter

[eluser]muzahir[/eluser]
Hi,

In codeigniter, i have to access the controller by giving its path e.g "http://www.test.com/system/application/c...loader.php" instead of "http://www.test.com/index.php/uploader" (as we use in CI).

But, when i access it by giving its path then i does not load the controller(parent class which i have extended) and i got the error so i can't get the $this (CI) object also for further use.

Please help me in finding the solution of my problem. is there any way to tackle that kind of problem.. i will be very pleased and thankful for your replies
