I've tried setting up a subdomain as an FTP CDN, and managed to get it to work, but now I'm wondering if I need to copy some of the htaccess code from the blog subdomain to the static subdomain
My blog is in one subdomain - blog.x.com
I've the static data in another subdomain - static.x.com and set up an ftp user account for it
It works, and W3C can transfer files without any problems (other than it has to use a passive FTP connection)
The .htaccess file in the static subdomain contains the command 'rewrite engine off' (this is needed to avoid one of the rules in the .htaccess for the main site), but thats all at present
It works, but I wonder if some of the stuff added to .htaccess for the blog would also be desirable for the static subdomain. (I guess that the usual setup would have the static subdomain as a subdirectory of the blog, and so inherit the .htaccess settings; this isn't the case here)
On the positive side, the tool to move everything into the media library and update all the posts is great (especially for cleaning up all the hotlinked files!) - that alone will speed up another older blog I have.
