Can't set cookie

[eluser]CroNiX[/eluser]
You can't read a cookie until the next request because it hasn't been written yet. It gets set when the whole page is sent as it gets transmitted along with the headers and not immediately when you call set_cookie(). The data is meant to be used in subsequent requests, not the current one.
