OT: apache in shared environment

[basti]

Hello,

my question is a bit OT but perhaps someone can help.
We use apache mpm_prefork and mod_itk in shared environment for 
privilege separation.

Now we want to use http2.

As I understod:

- mod_itk need mpm_prefork
- mpm_prefork is not compatibe with mod_http2

We have try to use mpm_event with PHP-fpm and different pools, but this 
separate the php stack only.

Is there a way to get http2 work with mod_itk?

Best regards
