Header addition with HTTP 2.0

Hi,

I work on a firewall, where we need to add a header to the client request
going to the server.

Topology is

Client -------> Firewall -------> Servers

Ex: Suppose a request is going to youtube, a new header "
X-YouTube-Edu-Filter" has to be added to the request.

In HTTP 1.0/1.1, this is feasible
I tried with SPDY as well and Server did accept the request and redirected
accordingly.

In HTTP 2.0, can i do this?
If a header is added at firewall, client and server dynamic tables might go
out of sync. Will it cause any issues?

Any suggestion is greatly appreciated.

Thanks
Vimala
