Among other things, it does not support the outdated mod_php Apache module, which in turn still operates many old websites, so enabling and enabling it is left to system administrators. In this short description, we will see how we can enable the use of the HTTP/2 protocol on Apache web servers that still use the old HTTP/1.1 protocol.
