Redirecting HTTPS traffic to HTTP

Yes, as long as it is applied to the HTTPS virtual server and the LTM is decrypting the traffic.

Although if you want a 301, you'll have to use the HTTP::respond command instead of the HTTP::redirect command which sends a 302:

when HTTP_REQUEST {
  if [HTTP::header "User-Agent"] starts_with "ua_text"
    HTTP::respond 301 "Location" "http://[getfield [HTTP::host] : 1][HTTP::uri]"
  } else {
    pool myPool
  }
}
