Can I do a exact match on the cdn domain and redirect to the main
domain? i.e. "cdn.example.com <http://cdn.example.com>" gets directed to
www.example.com <http://www.example.com>,
but cdn.example.com/images/abc.jpg
<http://cdn.example.com/images/abc.jpg> should not be redirected. Or is
there a better way?
Hi,
What I do (with no claim that it's the canonical, or even a better, solution) is
to put a rewrite rule on the origin server that says "if the request comes from
the CDN caches and is not for (jpg|gif|js|css|whatever) then issue a permanent
redirect to the canonical site".
So the CDN ends up storing pointers back to the canonical site for those
resources you do not wish served from CDN. The result being that, even if a user
does go to http://cdn.example.com/ they are bounced straight back to
http://www.example.com/).
HTH, etc,
Alex.
