Let’s say my controller function is expecting 2 parameters: page_name, and user_name

The URL would be in the format http://mysite.com/controller_name/function_name/page_name/user_name

Assuming that sometimes I can have a blank user_name, and other times I can have blank page_name, can I pass a blank page_name by loading this URL?
http://mysite.com/controller_name/function_name//user_name

If the controller function is:

function function_name($page_name="default", $user_name=null) 
...

Would the $page_name value be “default” for the 2nd URL stated above?

    You can’t. Server will simply ignore the extra slash.
    Since both parameters are optional, you should use request parameters.
    http://mysite.com/controller_name/function_name?page_name=p1&user_name=u1

    And in your controller, use $this->input->get('page_name') and $this->input->get('user_name') to get the value and check if the values are empty.
