  • If you install NGINX for your InMotion Hosting account, then it will automatically remove the HTTP/2 package for the Apache Web Server.
  • Remember that the domain using HTTP/2 must have a valid SSL certificate for HTTP/2 to work properly.
  • Apache offers three MPM modules: Prefork, Worker, and Event. HTTP/2 on Apache does not support the mpm_prefork module but you can use mpm_worker in its place. You can find more information on the different Multi-processing Modules (MPM) here. The removal of the mpm_prefork module will affect how your PHP code is handled. If you are not familiar with the multiprocessing modules and how it affects your PHP installation then consult with an experienced developer.
