h1. URL Redirection {{>toc}} h2. Module: mod_redirect *Module: mod_redirect* .. meta:: :keywords: lighttpd, redirect .. contents:: Table of Contents h2. Description The redirect module is used to specify redirects for a set of URLs. h2. Options h3. url.redirect Redirects a set of URLs externally e.g. <pre> url.redirect = ( "^/show/([0-9]+)/([0-9]+)$" => "http://www.example.org/show.php?isdn=$1&page$2", "^/get/([0-9]+)/([0-9]+)$" => "http://www.example.org/get.php?isdn=$1&page$2" ) # make an external redirect # from any www.host (with www.) to the host (without www.) $HTTP["host"] =~ "^www\.(.*)$" { url.redirect = ( "^/(.*)" => "http://%1/$1" ) } </pre> Note that the "%1" in the url.redirect target refers to the parenthesized subexpression in the conditional regexp (.*). It does *not* necessarily have the meaning that "%1" would have in evhost.path-pattern (where it would mean 'top-level domain'). If url.redirect is specified within a regex conditional, % patterns are replaced by the corresponding groups from the condition regex. %1 is replaced with the first subexpression, %2 with the second, etc. %0 is replaced by the entire substring matching the regexp. See above and below for examples using % patterns. h3. url.redirect-code (Added in 1.5.0) Defines the http code that is sent with the redirect URL e.g. <pre> url.redirect-code = 302 </pre> h2. Example Some people love the www part in the url. A general solution to move all non www. hosts to its www equivalent: :: <pre> $HTTP["host"] =~ "^([^.]+\.[^.]+)$" { url.redirect = ( ".*" => "http://www.%1" ) } </pre> Moving any subdomains except a few to www.example.org: (Note: The second match is required since a non-match doesn't set any groups) :: <pre> $HTTP["host"] !~ "^(www|mail|mysql)\.(example\.org)$" { $HTTP["host"] =~ "^(.+\.)?(example\.org)$" { url.redirect = ( "^/(.*)" => "http://www.%2/$1" ) } } </pre>
