Is it possible add new header after BotDefense profile execution but before&nbsp;an HTTP request is sent to the server-side when HTTP2 used? For HTTP 1.1 I can use HTTP\_REQUEST\_SEND. What is about HTTP2?

You talk about HTTP/2 Full Proxy Setup? As I described in my article the HTTP\_REQUEST\_SEND event is not triggered and I have not found an adequate event.

Have you tried the BOTDEFENSE\_ACTION event?

Yes, BOTDEFENSE\_REQUEST or BOTDEFENSE\_ACTION not help.

HTTP/2 Full Proxy or HTTP/2 on Server Side with HTTP MRF Router are not execute HTTP\_REQUEST\_SEND event.
