Flashdata and refresh

[eluser]mighty_falcon[/eluser]
I am having an issue with flashdata. Up to now throughout my application when I have had the need to use flashdata I have first set it in my controller and then redirected to the next one and accessed it from there without any problems.

For this one page however I need to set the flashdata in the Cart controller like this:

Code:

$this->session->set_flashdata('redirect_url', site_url('cart'));

And then link to the login page in the view of the cart controller:

Code:

<a href="&lt;?= site_url('auth/login')?&gt;">login</a>

And then be able to access the flashdata in the login controller, which I am not able to. If I place a refresh in the cart controller right after setting the flashdata it works okay.

Is there a workaround to this problem? I need to link to the login controller but cannot refresh to be able to access the flashdata...

Thanks!
