Hi Gary,

its indeed not an easy task without changing the entire data group structure... 😉

The script below is the best I can do for you...

when HTTP_REQUEST {
    set low_host_path [string tolower [HTTP::host][HTTP::path]
    if { $low_host_path equals "ou.edu/" } then {
        HTTP::redirect "http://www.ou.edu/"
    } elseif { $low_host_path equals "www.ou.edu/" } then {
        pool www_ou_edu_cms_servers
    } else {
        Lookup the redirect or pool based upon match_string value
        set goto [class match -value $low_host_path starts_with www_ou_edu_redir_class]
        switch -exact -- [getfield $goto "," 1] {
            "pool" { pool [getfield $goto "," 2] }
            "redir" { HTTP::redirect [getfield $goto "," 2] }
            default { pool ouwww_bostitch }
        }
    }
}

Cheers, Kai
