Description

The redirect module is used to specify redirects for a set of URLs.

Options

url.redirect

redirects a set of URLs externally

e.g.

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" )
}

url.redirect-code (Added in 1.5.0)

defines the http code that is sent with the redirect URL

e.g.

url.redirect-code = 302

Some people love the www part in the url. A general solution to move all non www. hosts to its www equivalent:

$HTTP["host"] =~ "^([^.]+\.[^.]+)$" {
  url.redirect = (
    ".*" => "http://www.%1"
  )
}

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)

$HTTP["host"] !~ "^(www|mail|mysql)\.(example\.org)$" {
  $HTTP["host"] =~ "^(.+\.)?(example\.org)$" {
    url.redirect = (
      "^/(.*)" => "http://www.%2/$1"
    )
  }
}
