+ * \brief Support for Private Asterisk HTTP Servers.
+ * \note Note: The Asterisk HTTP servers are extremely simple and minimal and
+ * only support the "GET" method.
+ *
+ * \author Mark Spencer <markster@digium.com>
+ *
+ * \note In order to have TLS/SSL support, we need the openssl libraries.
+ * Still we can decide whether or not to use them by commenting
+ * in or out the DO_SSL macro.
+ * TLS/SSL support is basically implemented by reading from a config file
+ * (currently http.conf) the names of the certificate and cipher to use,
+ * and then run ssl_setup() to create an appropriate SSL_CTX (ssl_ctx)
+ * If we support multiple domains, presumably we need to read multiple
+ * certificates.
+ * When we are requested to open a TLS socket, we run make_file_from_fd()
+ * on the socket, to do the necessary setup. At the moment the context's name
+ * is hardwired in the function, but we can certainly make it into an extra
+ * parameter to the function.
+ * We declare most of ssl support variables unconditionally,
+ * because their number is small and this simplifies the code.
+ *
+ * \note: the ssl-support variables (ssl_ctx, do_ssl, certfile, cipher)
+ * and their setup should be moved to a more central place, e.g. asterisk.conf
+ * and the source files that processes it. Similarly, ssl_setup() should
+ * be run earlier in the startup process so modules have it available.
