I am using phpbb forum, with some seo plugin, which turned all my dynamic urls "viewtopic.php?=1234" to SEO urls such as "/super-jackpot-t821.html". I was happy with it.
but now problme is, i have moved host, moved phpbb to sub folder and upgraded to latest phpbb. Now that plugin stopped working and all the urls are already indexed by google, yahoo etc.
So i was thinking is it possible to 301 redirect SEO urls back to normal urls? May be picking the last 821 number of seo url using HTACCESS and turning it back to viewtopic.php?t=821 ???
thankx.
Here's a htaccess guide i found.

to match 0 to 9999 the regex should be ^[0-9]{1,4}$
