-1. Overview
-
-   The SL module allows Kamailio to act as a stateless UA server and
-   generate replies to SIP requests without keeping state. That is
-   beneficial in many scenarios, in which you wish not to burden server's
-   memory and scale well.
-
-   The SL module needs to filter ACKs sent after a local stateless reply
-   to an INVITE was generated. To recognize such ACKs, Kamailio adds a
-   special "signature" in to-tags. This signature is sought for in
-   incoming ACKs, and if included, the ACKs are absorbed.
-
-   To speed up the filtering process, the module uses a timeout mechanism.
-   When a reply is sent, a timer is set. As time as the timeout didn't
-   hit, the incoming ACK requests will be checked using TO tag value. Once
-   the timer expires, all the ACK are let through - a long time passed
-   till it sent a reply, so it does not expect any ACK that have to be
-   blocked.
-
-   The ACK filtering may fail in some rare cases. If you think these
-   matter to you, better use stateful processing (tm module) for INVITE
-   processing. Particularly, the problem happens when a UA sends an INVITE
-   which already has a to-tag in it (e.g., a re-INVITE) and Kamailio want
-   to reply to it. Than, it will keep the current to-tag, which will be
-   mirrored in ACK. Kamailio will not see its signature and forward the
-   ACK downstream. Caused harm is not bad--just a useless ACK is
-   forwarded.
-
-2. Dependencies
-
-   2.1. Kamailio Modules
-   2.2. External Libraries or Applications
-
-2.1. Kamailio Modules
-
-   The following modules must be loaded before this module:
-     * TM - transaction module, if you want to use the transactional
-       send_reply functionality.
-
-2.2. External Libraries or Applications
-
-   The following libraries or applications must be installed before
-   running Kamailio with this module loaded:
-     * None.
-
-3. Exported Parameters
-
-   3.1. enable_stats (integer)
-   3.2. bind_tm (integer)
-
-3.1. enable_stats (integer)
-
-   If the module should generate and export statistics to the core
-   manager. A zero value means disabled.
-
-   SL module provides statistics about how many replies were sent (
-   splitted per code classes) and how many local ACKs were filtered out.
-
-   Default value is 1 (enabled).
-
-   Example 1.1. enable_stats example
-modparam("sl", "enable_stats", 0)
-
-3.2. bind_tm (integer)
-
-   If the module should use transaction support for sending the replies. A
-   zero value means disabled.
-
-   Module tm should be loaded before of this one
-
-   Default value is 1 (enabled).
-
-   Example 1.2. bind_tm example
-modparam("sl", "bind_tm", 0)
-
-4. Exported Functions
-
-   4.1. sl_send_reply(code, reason)
-   4.2. send_reply(code, reason)
-   4.3. sl_reply_error()
-
-4.1.  sl_send_reply(code, reason)
-
-   For the current request, a reply is sent back having the given code and
-   text reason. The reply is sent stateless, totally independent of the
-   Transaction module and with no retransmission for the INVITE's replies.
-   'code' and 'reason' can contain pseudo-variables that are replaced at
-   runtime.
-
-   Meaning of the parameters is as follows:
-     * code - Return code.
-     * reason - Reason phrase.
-
-   This function can be used from REQUEST_ROUTE, ERROR_ROUTE.
-
-   Example 1.3. sl_send_reply usage
-...
-sl_send_reply("404", "Not found");
-...
-sl_send_reply("$err.rcode", "$err.rreason");
-...
-
-4.2.  send_reply(code, reason)
-
-   For the current request, a reply is sent back having the given code and
-   text reason. The reply is sent stateful or stateless, depending of the
-   Transaction module: if the transaction for current request has created,
-   then the reply is sent stateful, otherwise stateless.
-
-   Meaning of the parameters is as follows:
-     * code - Return code.
-     * reason - Reason phrase.
-
-   This function can be used from REQUEST_ROUTE, FAILURE_ROUTE,
-   BRANCH_ROUTE, ERROR_ROUTE.
-
-   Example 1.4. send_reply usage
-...
-send_reply("404", "Not found");
-...
-send_reply("403", "Invalid user - $fU");
-...
-
-4.3.  sl_reply_error()
-
-   Sends back an error reply describing the nature of the last internal
-   error. Usually this function should be used after a script function
-   that returned an error code.
-
-   This function can be used from REQUEST_ROUTE.
-
-   Example 1.5. sl_reply_error usage
-...
-sl_reply_error();
-...
-
-5. Exported Statistics

- *              w/ different values!)  (andrei)
- * 2003-03-06  aligned to request2response use of tag bookmarks (jiri)
- * 2003-04-04  modified sl_send_reply to use src_port if rport is present
- *              in the topmost via (andrei)
- * 2003-09-11: updated to new build_lump_rpl() interface (bogdan)
- * 2003-09-11: sl_tag converted to str to fit to the new
- *               build_res_buf_from_sip_req() interface (bogdan)
- * 2003-11-11: build_lump_rpl() removed, add_lump_rpl() has flags (bogdan)
- * 2004-10-10: use of mhomed disabled for replies (jiri)
- * 2006-03-29: callbacks for sending replies added (bogdan)
- * 2006-11-28: Moved numerical code tracking out of sl_send_reply() and into
- *             update_sl_reply_stat(). Also added more detail stat collection.
