| * request.c is the code which handles the main line of request |
| * processing, once a request has been read in (finding the right per- |
| * directory configuration, building it if necessary, and calling all |
| * the module dispatch functions in the right order). |
| * |
| * The pieces here which are public to the modules, allow them to learn |
| * how the server would handle some other file or URI, or perhaps even |
| * direct the server to serve that other file instead of the one the |
| * client requested directly. |
| * |
| * There are two ways to do that. The first is the sub_request mechanism, |
| * which handles looking up files and URIs as adjuncts to some other |
| * request (e.g., directory entries for multiviews and directory listings); |
| * the lookup functions stop short of actually running the request, but |
| * (e.g., for includes), a module may call for the request to be run |
| * by calling run_sub_req. The space allocated to create sub_reqs can be |
| * reclaimed by calling destroy_sub_req --- be sure to copy anything you care |
| * about which was allocated in its apr_pool_t elsewhere before doing this. |
