I am currently maintaining my site and i moved all the old stuff to old-site/ subfolder.
used META Tag.
here is the most important line
<META HTTP-EQUIV='refresh' content='0,http://404.bizhat.com/old-site/'>
by redirecting, i don't need to see millions of folder and images. simply one folder. however whenever I try to see it in IE by simply trying to go to 404.bizhat.com. i get 403 forbidden. wonder did the admin set it like this or i did something wrong.
