03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * @brief Apache Request library
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz/* http_request.c is the code which handles the main line of request
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * processing, once a request has been read in (finding the right per-
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * directory configuration, building it if necessary, and calling all
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * the module dispatch functions in the right order).
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * The pieces here which are public to the modules, allow them to learn
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * how the server would handle some other file or URI, or perhaps even
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * direct the server to serve that other file instead of the one the
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * client requested directly.
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * There are two ways to do that. The first is the sub_request mechanism,
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * which handles looking up files and URIs as adjuncts to some other
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * request (e.g., directory entries for multiviews and directory listings);
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * the lookup functions stop short of actually running the request, but
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * (e.g., for includes), a module may call for the request to be run
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * by calling run_sub_req. The space allocated to create sub_reqs can be
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * reclaimed by calling destroy_sub_req --- be sure to copy anything you care
03bdb4fb430b0d4e502ddfc75f7e9dbd91db72e9nd * about which was allocated in its apr_pool_t elsewhere before doing this.
