http://example.com/773 to http://blog.example.com/773

or

http://example.com/482/comment... to http://blog.example.com/482/comment...

and redirect urls contain “tag”, example :

http://example.com/tag/free-psd to http://blog.example.com/tag/free-psd

or

http://example.com/tag/jquery to http://blog.example.com/tag/jquery

and not redirect URLs contain strings like this :

http://example.com/web or http://example.com/web/shop or http://example.com/about
