It is now consider as 302 redirect and it is very dangerous.

Links from other sites can be dangerous because of the way that Google and MSN handle 302 redirects - they sometimes attribute the target page's assets to the linking page, and the linking page can end up taking the place of the target page in the search results. Most small directories that do not link directly to the target page, use the 302 method, and are dangerous to the listed pages because of this.
Is there a way to change this mod such that this does not happen? I've been reading through the code, and I'm uncertain whether or not it can be done.
