Changes with nginx 0.7.10 13 Aug 2008v0.7.10

    *) Bugfix: in the "addition_types", "charset_types", "gzip_types",
       "ssi_types", "sub_filter_types", and "xslt_types" directives; the
       bugs had appeared in 0.7.9.

    *) Bugfix: of recursive error_page for 500 status code.

    *) Bugfix: now the ngx_http_realip_module set address not for whole
       keepalive connection, but for each request passed via the connection.

+
+    *) Исправление: ошибок в директивах addition_types, charset_types,

+       этому соединению.
