I recently did a big update on my wordpress site, thus some old permalink are invlid now.
Seach google for a tutorial on this and found a lot about static html page redirection examples or specific php page which are not what i'm looking for
Both my old and new permalinks are in path format, for example, i need redirect a couple urls of old gallery posts (deleted) which are
/2009/06/gallery/abc/ /2009/06/gallery/cba/ /2009/06/gallery/bbc/ /2009/06/gallery/aab/
to a new page which is
How do i write a correct redirect rule for this?
