301 redirect to an external site [Solved]

[eluser]ajitabhpandey[/eluser]
Hi,

The documentation for the redirect() function of URL Helper says that it is meant for redirection within site, but the application which I am writing have to redirect the URL to a another website using 301 redirect at some point in the code. How can I achieve that in CI? Is there a library function which I missed out in the documentation or I need to write one of my own? If later then any tips on what minimum headers needs to be set using Output class and then how do I send the headers to browser.

Thanks.
