how to create 301 redirect in codeigniter

thanks for the input!

I'd like to redirect the old url's to it's new path but per requirements, the client wants it to redirect to it's homepage

This should i suggest to them for better SEO!

I also, tried your suggestion about redirecting old urls to it's new path..and it works

what i did is i re-route my old url to a new member function in my controller

old path:
page/view/$1

new path:
page/$1

routes:
page/view/$1 = 'page/redirect_old_path/$1'
page/$1 = 'page/new_url_page/$1'

where the redirect_old_path member function redirects to 'page/new_url_page/$1'

Im just a newbie in CI, any suggestion on how to improve this approach are welcome!

Thanks Aken for the help!
