/**
 * Manages the request mappings. It includes the internal mapper and all
 * properties associated with a location ( or virtual host ). The information
 * is set using:
 *   - various autoconfiguration mechanisms.
 *   - uriworkers.properties
 *   - JkMount directives
 *   - <SetHandler> and apache specific directives.
 *   - XXX workers.properties-like directives ( for a single config file )
 *   - other server-specific directives
 *
 * The intention is to allow the user to use whatever is more comfortable
 * and fits his needs. For 'basic' configuration the autoconf will be enough,
 * server-specific configs are the best for fine-tunning, properties are
 * easy to generate and edit.
