Redirect

[eluser]james byrne[/eluser]
I have a problem in my application, it is just a simple login now. But when the user logins in, which uses the login function. It woks fine, But if for some reason i then load the index function or refresh the page. It redirects to the login function, which because the user is logged in redirects back to index. So it gets in a big loop. I can post the code if needed but can someone give me a idea of what is going on here. and why? Thanks in advance.
