having problem creating a default controller

[eluser]UdayD[/eluser]
sorry for the earlier mistake i've made.
my code is as below

Code:

class main extends Controller
{
    function main()
    {
         parent::controller();
    }

function page()
{
$this->load->view('main');
}
}

here i have a view as main.php and a controller as main.php in the controller i have a function page which i have to call when my default controller loads.
So my question is do i need to write an index funtion instead of page function. or how will my page functions get called when my user access following url

Code:

http://server.com/index.php

this url must call my page function which will load my main view.
