regex - 301 redirect to the rewrited url -

the cms working has these rewrite rules:

for tags:

rewriterule ^tags/([^/]+)/$ tag.php?t=$1&page=1 rewriterule ^tags/([^/]+)/page-([0-9]+)(/)?$ tag.php?t=$1&page=$2 

for category pages:

rewriterule ^browse-(.*)-videos.html$ category.php?cat=$1 rewriterule ^browse-(.*)-videos-([0-9]+)-(.*).html$ category.php?cat=$1&page=$2&sortby=$3 

but not redirect seo friendly url estructure creating duplicate content issues, how can make 301 redirects rewrited url if accessed other?

thanks in advance

you need create 4 new rules , place them above existing.

#redirect old url new seo rewritecond %{the_request} ^get\ /+tag\.php\?t=([^&\s]+)&page=1 rewriterule ^ /tags/%1/? [r=301,l] #redirect old url new seo rewritecond %{the_request} ^get\ /+tag\.php\?t=([^&\s]+)&page=([^&\s]+) rewriterule ^ /tags/%1/page-%2/? [r=301,l] #redirect old url new seo rewritecond %{the_request} ^get\ /+category\.php\?cat=([^&\s]+)&page=([^&\s]+)&sortby=([^&\s]+) rewriterule ^ /browse-%1-videos-%2-%3.html? [r=301,l] #redirect old url new seo rewritecond %{the_request} ^get\ /+category\.php\?cat=([^&\s]+) rewriterule ^ /browse-%1-videos.html?
