Paid half a day to investigate the redirection problem, even the staff of IXWebHost said there is no way. Finally, made it work:
1. Make sure alias and sub-domains related to photo.tale365.com are cleared. To avoid the confusion of different effects.
2. Make sure A record in DNS configuration pointed photo.tale365.com to the correct IP address. So that this URL can direct to the website and reach .htaccess.
3. Edit .htaccess and added below lines
RewriteCond %{HTTP_HOST} ^photo.*\.tale365\.com$ [nocase]
RewriteRule ^(.*)$ http://www.flickr.com/photos/librazh/$1 [redirect=301,last]
It means if the URL starts with “http://”, the rest part starts from “photo” and ends with “tale365.com” regardless the cases, then append everything to the URL of flickr album where the “$1” placed.
4. Wait for DNS to propagate the changes.
