Run-Time Configuration Changes

Your existing version 2.0 config files and startup scripts can usually be used unchanged in version 2.2. Some small adjustments may be necessary for particular configurations as discussed below. In addition, if you dynamically load the standard modules using the LoadModule directive, then you will need to account for the module name changes mentioned above.

If you choose to use the new default configuration file for version 2.2, you will find that it has been greatly simplified by removing all but the most essential configuration settings. A set of example configuration settings for more advanced features is present in the conf/extra/ directory of the installed server. Default configuration files are installed in the conf/original directory.
