With Apache we can do this using:

RewriteCond %{HTTP_USER_AGENT} !^CDN_USER_AGENT$ [NC]
RewriteRule .*\.(jpg|gif|png|flv|css|js|swf)$
http://cdn-domain-name/$0 [R=301,L]

But we want our CDN to serve our static content, what would be easier
to accomplish this?

I tried:

rewrite ^/*\.(jpg|gif|png|flv|css|js|swf)$
http://http.cdnlayer.com/contentfolder$1 last;

But it didn't work.

Should I be using a location instead?

location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ {
access_log off;
expires 30d;
}

Like the above ones? but how would the rewrite portion come into play?

Thanks!
