Method appendPath

plugins/cachekey/cachekey.cc:437–483

* @brief Appends to the cache key the path from the URI (default), regex capture/replacement from the URI path, * regex capture/replacement from URI as whole. * @note A path is always defined for a URI, though the defined path may be empty (zero length) (RFC 3986) * @param pathCapture if not empty will append regex capture/replacement from the URI path * @param pathCaptureUri if not empty will

 * @todo enhance, i.e. /<regex>/<replace>/
