Web servers
In the WebSphere Application Server product, an application server works with a Web server to handle requests for Web applications. The application Server and Web server communicate using a WebSphere HTTP plug-in for the Web server.For more information, refer to Introduction: Web servers.
Cell-wide settings
Cell-wide settings are sets of configuration data that are stored in files in the cell directory. These configuration files are replicated to every node in the cell. Several different configuration settings apply to the entire cell. These settings include the definition of virtual hosts, shared libraries, and any variables that must be consistent throughout the entire cell.For more information, refer to Introduction: Cell-wide settings.
Variables
A variable is a configuration property that can be used to provide a parameter for any value in the system. A variable has a name and a value to use in place of that name wherever the variable name is located within the system.For more information, refer to Introduction: Variables.
