To run Dokuwiki on Hiawatha, you need the following UrlToolkit rule for URL rewriting:

UrlToolkit {
    ToolkitID = dokuwiki
    Match ^/(bin|conf|data|inc)/ DenyAccess
    Match ^/_media/(.*)\?(.*) Rewrite /lib/exe/fetch.php?media=$1&$2
    Match ^/_media/(.*) Rewrite /lib/exe/fetch.php?media=$1
    Match ^/_detail/(.*)\?(.*) Rewrite /lib/exe/detail.php?media=$1&$2
    Match ^/_detail/(.*) Rewrite /lib/exe/detail.php?media=$1
    Match ^/_export/([^/]+)/(.*) Rewrite /doku.php?do=export_$1&id=$2
    Match ^/$ Rewrite /doku.php
    RequestURI exists Return
    Match /(.*)\?(.*) Rewrite /doku.php?id=$1&$2
    Match /(.*) Rewrite /doku.php?id=$1
}
