What does the MACH_CONFIG_MODE variable in the index.cfm file of the skeleton or my Application.cfc do?
This variables tells Mach-II when the configuration file (mach-ii.xml) should be reloaded to reconfigure your application components and model. The MACH_CONFIG_MODE variable takes the following values:
MACHII_CONFIG_MODE
| Value | Meaning | Description | Recommended For | Not Recommended For |
| -1 | Never reload | Does not reload the mach-ii.xml configuration file | - Production environments | - Development environments |
| 0 | Dynamic reload | Reloads the configuration file whenever the base, includes or module XML config files is updated by automatically checking when the file was last modified and size of file. If a module or module include file changes, only that module is reloaded. | - Development environments | |
| 1 | Always reload | Reloads the configuration for each request. Each time the configuration is reloaded, the application framework is reinstantiated. This means lots of object instances are created and the mach-ii.xml file is reread from file and reparsed. This also means any state information held in framework components (such as Listeners) will be reset if not persisted. | - Development environments - debugging only | Production environments (it results in significant performance penalties) |
