[biohavok]

i have line in my htaccess file\[code\]**Redirect /poppin http://www.mysite.com/category.html**\[/code\]so if some one enters\[code\]http://www.mysite.com/popin\[/code\] it is redirecting to \[code\]http://www.mysite.com/category.html\[/code\]but if someone type url like :\[code\]http://www.mysite.com/popin/\[/code\] it is redirecting to not found page so last slash at the end of url is redirecting it to not found pagei want to make change in my htaccess file such that if anyone enters \[code\]www.mysite.com/poppin\[/code\] or \[code\]www.mysite.com/poppin/\[/code\] it should redirect to \[code\]www.mysite.com/category.html\[/code\]
