I have a fully functioning WPMU instance running a few sites using the sub-folder method. The .htaccess file in /var/www/html is configured per the WP codex and is working fine. I have also confirmed that "AllowOverride" is set to All.
On one of my sites, I want to redirect a sub-folder of the "files" directory to the Amazon S3. I've added an .htaccess file to:
wp-content/blogs.dir/5/files/2011 to handle the redirect.
If I visit an image directly it works, the redirect fires and the image is served from the S3:
However, if I access the same image using the standard WPMU convention, it fails:
Does this have to do with "chaining" .htaccess redirects? Any suggestions would be greatly appreciated!
