additional conditions on an irule

This seems to work but is not as Eloquent as what has been provided from here..

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