hi,
thank you for your help.
I know have a simple problem, but in all my tests didn't work, so I thought I should let the experts have an opinion
so I need all URL's of this format
www.site.com/ip-XXXX.html?id_cfm=XXXX (XX being digits)
301 redirected to www.site.com/ip-XXXX.html
(they are now seen as duplicates by google, but they are not)
RewriteRule ^/ip-(.*)\.html?id_cfm=(.*)$ /ip-$1.html [R=301,L]
is simply ignored...
