Redirect to absolute URL

[eluser]maesk[/eluser]
Hi,

the URL Helper's redirect() function does a header redirect to a local URI, that is a relative URL. Sometimes, however, I'll have to redirect to an absolute URL, for example when I have an optional number of parameters for my controller. Should I just use

Code:

header('Location: http://www.example.com/');

for these cases or is there a CI specific method to do this?
