[2] C++11 introduces the thread_local [3] keyword which can be used in the following cases Namespace level (global) variables; File static variables

A typical front controller structure. Front controllers are often used in web applications to implement workflows. While not strictly required, it is much easier to control navigation across a set of related pages (for instance, multiple pages used in an online purchase) from a front controller than it is to assign individual pages responsibility for navigation.

Diagram of interactions in MVC's Smalltalk-80 interpretation. Model–view–controller (MVC) is a software design pattern [1] commonly used for developing user interfaces that divides the related program logic into three interconnected elements. These elements are:
The reactor software design pattern is an event handling strategy that can respond to many potential service requests concurrently.The pattern's key component is an event loop, running in a single thread or process, which demultiplexes incoming requests and dispatches them to the correct request handler.
If this number is reached and a new item is requested, an exception may be thrown, or the thread will be blocked until an object is released back into the pool. The object pool design pattern is used in several places in the standard classes of the .NET Framework. One example is the .NET Framework Data Provider for SQL Server.
The Spring Framework is an application framework and inversion of control container for the Java platform. [2] The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform.
