+
+The `ngx_http_access_module` module allows
+limiting access to certain client addresses.
+
+Access can also be limited by
+[password](/nginx/module-reference/http/ngx_http_auth_basic_module), by the
+[result of subrequest](/nginx/module-reference/http/ngx_http_auth_request_module),
+or by [JWT](/nginx/module-reference/http/ngx_http_auth_jwt_module).
+Simultaneous limitation of access by address and by password is controlled
+by the [satisfy](/nginx/module-reference/http/ngx_http_core_module#satisfy) directive.
+## Example Configuration
+
+
+```nginx
+location / {
+    deny  192.168.1.1;
+    allow 192.168.1.0/24;
+    allow 10.1.1.0/16;
+    allow 2001:0db8::/32;
+    deny  all;
+}
+
+```
+
+
+The rules are checked in sequence until the first match is found.
+In this example, access is allowed only for IPv4 networks
+`10.1.1.0/16` and `192.168.1.0/24`
+excluding the address `192.168.1.1`,
+and for IPv6 network `2001:0db8::/32`.
+In case of a lot of rules, the use of the
+[ngx_http_geo_module](/nginx/module-reference/http/ngx_http_geo_module)
+module variables is preferable.
+## Directives
+
+### allow
+
+{{< call-out >}}
+
+**Syntax:** allow `address` | `CIDR` | `unix:` | `all`
+
+**Default:** -
+
+**Context:** http, server, location, limit_except
+
+
+{{</call-out>}}
+
+
+Allows access for the specified network or address.
+If the special value `unix:` is specified (1.5.1),
+allows access for all UNIX-domain sockets.
+### deny
+
+{{< call-out >}}
+
+**Syntax:** deny `address` | `CIDR` | `unix:` | `all`
+
+**Default:** -
+
+**Context:** http, server, location, limit_except
+
+
+{{</call-out>}}
+
+
+Denies access for the specified network or address.
+If the special value `unix:` is specified (1.5.1),
+denies access for all UNIX-domain sockets.

+
+The `ngx_http_addition_module` module is a filter
+that adds text before and after a response.
+This module is not built by default, it should be enabled with the
+`--with-http_addition_module`
+configuration parameter.
+## Example Configuration
+
+
+```nginx
+location / {
+    add_before_body /before_action;
+    add_after_body  /after_action;
+}
+
+```
+
+## Directives
+
+### add_before_body
+
+{{< call-out >}}
+
+**Syntax:** add_before_body `uri`
+
+**Default:** -
+
+**Context:** http, server, location
+
+
+{{</call-out>}}
+
+
+Adds the text returned as a result of processing a given subrequest
+before the response body.
+An empty string (`""`) as a parameter cancels addition
+inherited from the previous configuration level.
+### add_after_body
+
+{{< call-out >}}
+
+**Syntax:** add_after_body `uri`
+
+**Default:** -
+
+**Context:** http, server, location
+
+
+{{</call-out>}}
+
+
+Adds the text returned as a result of processing a given subrequest
+after the response body.
+An empty string (`""`) as a parameter cancels addition
+inherited from the previous configuration level.
+### addition_types
+
+{{< call-out >}}
+
+**Syntax:** addition_types `mime-type` ...
+
+**Default:** text/html
+
+**Context:** http, server, location
+
+_This directive appeared in version 0.7.9._
+
+
+{{</call-out>}}
+
+
+Allows adding text in responses with the specified MIME types,
+in addition to “`text/html`”.
+The special value “`*`” matches any MIME type (0.8.29).
