Passenger::StandardApplicationPool Class Reference
[Apache-independent support classes and function]

#include <StandardApplicationPool.h>

Inheritance diagram for Passenger::StandardApplicationPool:

Passenger::ApplicationPool

List of all members.


Detailed Description

A standard implementation of ApplicationPool for single-process environments.

The environment may or may not be multithreaded - StandardApplicationPool is completely thread-safe. Apache with the threading MPM is an example of a multithreaded single-process environment.

This class is unusable in multi-process environments such as Apache with the prefork MPM. The reasons are as follows:

(Of course, StandardApplicationPool is usable if each process creates its own StandardApplicationPool object, but that would defeat the point of having a shared pool.)

For multi-process environments, one should use ApplicationPoolServer instead.
