301 redirect to full path

问题

I have a lot incorrect back links, the links are pointing to:

http://www.domain.com/tags/keyword

while the correct path is

http://www.domain.com/tags/keyword/

there are hundreds of those...how could i 301 redirect from the wrong links to the correct links?

Thank you so much in advance

You can try this code:

RewriteBase /
RewriteRule ^tags/([^/]+)$ /tags/$1/ [L,R=301]

• RewriteBase / tells apache that your URI starts by a /. If your site was in a subfolder you should write RewriteBase /subfolder/ instead.
• ^tags/([^/]+)$: you search for an URI starting with tags/ followed by [^/]+ that means any characters except /. The ( ) around it are there to capture it and use it in the redirection. So we capture any characters that are not / between tags/.../ in the URI. (^ marks the start of the string while $ marks the end)
• /tags/$1/ is the redirection. $1 means the first previous captured element (the one witch was between ( )).
• [L,R=301] indicates to apache that it should stop process other rules and redirect with a 301 header code.
