Access get parameter

[eluser]nk94555[/eluser]
Hi,

I am trying to get value of "ru" from the following url:

http://localhost/medibid/login?ru=http:/...est/view/1

I am not able to read "ru" in controller using $this->input->get('ru'). "ru" will be used to redirect users after login.

I have set $config['enable_query_strings'] = TRUE; in config file and if I set $config['uri_protocol'] = "PATH_INFO"; I get redirected to home page.

Any help with above is appreciated.

Thanks
Neeraj
