示例1: processRequest
/**
* @brief Process an incoming HTTP request.
*
* We look at the path of the request and see if it has a matching path handler. If it does,
* we invoke the handler function. If it does not, we try and find a file on the file system
* that would resolve to the path.
*
* @param [in] mgConnection The network connection on which the request was received.
* @param [in] message The message representing the request.
