Inter-process Communication for Apache Server and Nginx

For Nginx and Apache httpd web server, there usually exist several processes there for certain modes. For example, there is a master process and several worker processes.

How these processes communicate with each other? It seems that they use a file to communicate. I do not know if it is right and need further explanation.

Nginx uses Unix domain sockets to communicate with the workers. You can see them being created and being written to and read from in the nginx source.
