Sorry if I'm missing the point but I've just seen this thread. It might
sound obvious, but have you tried just doing a simple redirect? Just
sticking a redirect in a page on it's own and then calling it through the
browser. The other thing, and it might just be a typo is that you seem to
have a " missing in your redirect line (Might be my Mac not displaying the
right character):
header("Location: http://www.example.com/taskcomplete.htm:);
