In htaccess, I'd like to replace underscores with hyphens and then redirect the user the new url

I\'d like to redirect any request that contains underscores to the same url, but with hyphens replacing the urls. I\'ve seen a lot of forums suggest I do something like this

Answer 1

See the "Next" directive/rewrite flag, which causes the ruleset to be reevaluated starting with the first rule: http://httpd.apache.org/docs/current/rewrite/flags.html#flag_n

Something like this might work:

RewriteRule (.*)_(.*) $1-$2 [N]
