HTTPS Traffic to redirect into HTTP

If you are running v11.4.0 or later, it may be better to do this without iRules in local traffic policy. If not yet running v11.4.0 or higher, use this iRule and apply to your port 443 virtual server (assuming you have a separate virtual server for 80 and 443. If not, create separate ones):

when HTTP_REQUEST {
  HTTP::redirect http://[getfield [HTTP::host] ":" 1][HTTP::uri]
}
