any piece of advice on this? not fammiliar apache if tried find answer online, haven't figured out yet. in advance!

something should work in .htaccess:

rewriterule (*.html) http://www.your.site [r=301,l] 

if have other rules, can add afterwards long have l flag. stop processing rules once 1 matched. e.g.

rewriterule page.html http://www.your.site/page [r=301,l] rewriterule (*.html) http://www.your.site [r=301,l]
