Syntax: scgi_buffers number size; Default: scgi_buffers 8 4k|8k; Context: http, server, location Sets the number and size of the buffers used for reading a response from the SCGI server, for a single connection. By default, the buffer size is equal to one memory page. This is either 4K or 8K, depending on a platform.

Syntax: scgi_buffer_size size; Default: scgi_buffer_size 4k|8k; Context: http, server, location Sets the size of the buffer used for reading the first part of the response received from the SCGI server. This part usually contains a small response header. By default, the buffer size is equal to one memory page. This is either 4K or 8K, depending on a platform. It can be made smaller, however.

Syntax: scgi_buffering on | off; Default: scgi_buffering on; Context: http, server, location Enables or disables buffering of responses from the SCGI server. When buffering is enabled, nginx receives a response from the SCGI server as soon as possible, saving it into the buffers set by the scgi_buffer_size and scgi_buffers directives. If the whole response does not fit into memory, a part of it can be saved to a temporary file on the disk. Writing to temporary files is controlled

Syntax: satisfy all | any; Default: satisfy all; Context: http, server, location Allows access if all (all) or at least one (any) of the ngx_http_access_module, ngx_http_auth_basic_module, ngx_http_auth_request_module, or ngx_http_auth_jwt_module modules allow access. Example: location / { satisfy any; allow 192.168.1.0/32; deny all; auth_basic "closed site"; auth_basic_user_file conf/htpasswd; }

Syntax: scgi_bind address [transparent] | off; Default: — Context: http, server, location Makes outgoing connections to an SCGI server originate from the specified local IP address with an optional port (1.11.2). Parameter value can contain variables (1.3.12). The special value off (1.3.12) cancels the effect of the scgi_bind directive inherited from the previous configuration level, which allows the system to auto-assign the local IP address and port. The transparen

Syntax: rewrite_log on | off; Default: rewrite_log off; Context: http, server, location, if Enables or disables logging of ngx_http_rewrite_module module directives processing results into the error_log at the notice level.

Syntax: root path; Default: root html; Context: http, server, location, if in location Sets the root directory for requests. For example, with the following configuration location /i/ { root /data/w3; } The /data/w3/i/top.gif file will be sent in response to the “/i/top.gif” request. The path value can contain variables, except $document_root and $realpath_root. A path to the file is constructed by merely adding a URI to the value of the root directive. If a URI has to

Syntax: rewrite regex replacement [flag]; Default: — Context: server, location, if If the specified regular expression matches a request URI, URI is changed as specified in the replacement string. The rewrite directives are executed sequentially in order of their appearance in the configuration file. It is possible to terminate further processing of the directives using flags. If a replacement string starts with “http://”, “https://”, or “$scheme”, the processing stops

Syntax: return value; Default: — Context: server Specifies a value to send to the client. The value can contain text, variables, and their combination.

Syntax: return code [text];return code URL;return URL; Default: — Context: server, location, if Stops processing and returns the specified code to a client. The non-standard code 444 closes a connection without sending a response header. Starting from version 0.8.42, it is possible to specify either a redirect URL (for codes 301, 302, 303, and 307), or the response body text (for other codes). A response body text and redirect URL can contain variables. As a special case, a redir
