You should use some external memory for Apache processes.

The main options:

  • Database.
  • Shared memory (OS dependent).
  • Another process and use of an IPC mechanism (e.g. socket)
  • File.

Which one is right depends on your requirements, and you can combine them. For example, a “database” is actually implemented as another process that makes things persistent in a file and deals with concurrency problems in a known manner.
