additional conditions on an irule

ok this is what i ended up with...

when HTTP_REQUEST {
  set the variable with the host and path value
   set low_host_path [string tolower [HTTP::host][HTTP::path]]
    check for ou.edu/
    if { $low_host_path equals "ou.edu/" }{
        HTTP::redirect "http://www.ou.edu/"
     check for www.ou.edu/
  } elseif { $low_host_path equals "www.ou.edu/" }{
        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 [getfield $goto "," 1] {
      "pool" { pool [getfield $goto "," 2] }
      "redir" { HTTP::redirect [getfield $goto "," 2] }
      default { pool ouwww_bostitch }
    }
  }
}
