Simple iRule failing

You have an upper case S in your "contains", but you've used string tolower. The following is a tad more efficient if you are only concerned with the path, and not the parameters. Also, you should probably scrub your code prior to posting next time:

when HTTP_REQUEST {
  if { [string tolower [HTTP::path]] contains "/httpservices/login/loginservice.aspx"} {
    HTTP::redirect https://login.devstage1.weightwatchers.com/mobilelogin/mobile
    log local0. "Chassis Redirect"
    }
}
