Eeww, top posting...
One important note beyond the link Or gave is to stress the "301" part.
All of the "300" codes are redirects, and the article does not put a big
enough stress on this point.
301 means "permanent redirect". If the RFC is to be believed, this means
the request can be cached, bookmarks may be automatically updated, and
anything else that needs to take place (i.e. - updating the search
engine page rank) to facilitate the change. The URL is never coming back.
The most common way to produce redirects in Apache is mod_rewrite. The
problem is that mod_rewrite produces 302 (found elsewhere). This code is
for temporary redirects. The redirect may not be cached, bookmarks must
not be updated, and in any other sense the pointer that led you to the
original URL must still be considered valid. Understandably, Google will
also not assign the previous page's rank to the new address, as the
relocation is not considered permanent.
In mod_rewrite, to achieve 301 codes, either add [permanent] to the end
of the rule, or [R=301].
