Can a custom HTTP monitor work with a JSON response?

If you're intending to pass encrypted traffic to an HTTPS server for only this traffic, and all other traffic unencrypted to the default pool, you'd need to apply a serverSSL profile to the virtual and selectively disable SSL on the server side like this:

when HTTP_REQUEST {
  set reencrypt 0
  if { [HTTP::uri] contains "node=alpha" }{
    node xxx.xxx.xxx.xxx 443
    set reencrypt 1
  }
}
when SERVER_CONNECTED {
  if { $reencrypt == 0 }{
    SSL::disable
  }
}
