Syntax: fastcgi_temp_path path [level1 [level2 [level3]]]; Default: fastcgi_temp_path fastcgi_temp; Context: http, server, location Defines a directory for storing temporary files with data received from FastCGI servers. Up to three-level subdirectory hierarchy can be used underneath the specified directory. For example, in the following configuration fastcgi_temp_path /spool/nginx/fastcgi_temp 1 2; a temporary file might look like this: /spool/nginx/fastcgi_

Syntax: perl module::function|'sub { ... }'; Default: — Context: location, limit_except Sets a Perl handler for the given location.

Syntax: proxy_cache_revalidate on | off; Default: proxy_cache_revalidate off; Context: http, server, location This directive appeared in version 1.5.7. Enables revalidation of expired cache items using conditional requests with the “If-Modified-Since” and “If-None-Match” header fields.

Syntax: proxy_next_upstream error | timeout | invalid_header | http_500 | http_502 | http_503 | http_504 | http_403 | http_404 | non_idempotent | off ...; Default: proxy_next_upstream error timeout; Context: http, server, location Specifies in which cases a request should be passed to the next server: error an error occurred while establishing a connection with the server, passing a request to it, or reading the response header; tim

Syntax: worker_processes number | auto; Default: worker_processes 1; Context: main Defines the number of worker processes. The optimal value depends on many factors including (but not limited to) the number of CPU cores, the number of hard disk drives that store data, and load pattern. When one is in doubt, setting it to the number of available CPU cores would be a good start (the value “auto” will try to autodetect it). The auto parameter is supported starting from versions 1.

Syntax: scgi_limit_rate rate; Default: scgi_limit_rate 0; Context: http, server, location This directive appeared in version 1.7.7. Limits the speed of reading the response from the SCGI server. The rate is specified in bytes per second. The zero value disables rate limiting. The limit is set per a request, and so if nginx simultaneously opens two connections to the SCGI server, the overall rate will be twice as much as the specified limit. The limitation works only if buffering o

Syntax: proxy_cache_max_range_offset number; Default: — Context: http, server, location This directive appeared in version 1.11.6. Sets an offset in bytes for byte-range requests. If the range is beyond the offset, the range request will be passed to the proxied server and the response will not be cached.

Syntax: userid_expires time | max | off; Default: userid_expires off; Context: http, server, location Sets a time during which a browser should keep the cookie. The parameter max will cause the cookie to expire on “31 Dec 2037 23:55:55 GMT”. The parameter off will cause the cookie to expire at the end of a browser session.

Syntax: proxy_method method; Default: — Context: http, server, location Specifies the HTTP method to use in requests forwarded to the proxied server instead of the method from the client request. Parameter value can contain variables (1.11.6).

Syntax: fastcgi_send_lowat size; Default: fastcgi_send_lowat 0; Context: http, server, location If the directive is set to a non-zero value, nginx will try to minimize the number of send operations on outgoing connections to a FastCGI server by using either NOTE_LOWAT flag of the kqueue method, or the SO_SNDLOWAT socket option, with the specified size. This directive is ignored on Linux, Solaris, and Windows.
