Syntax: fastcgi_buffer_size size; Default: fastcgi_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 FastCGI 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: fastcgi_cache zone | off; Default: fastcgi_cache off; Context: http, server, location Defines a shared memory zone used for caching. The same zone can be used in several places. Parameter value can contain variables (1.7.9). The off parameter disables caching inherited from the previous configuration level.

Syntax: fastcgi_busy_buffers_size size; Default: fastcgi_busy_buffers_size 8k|16k; Context: http, server, location When buffering of responses from the FastCGI server is enabled, limits the total size of buffers that can be busy sending a response to the client while the response is not yet fully read. In the meantime, the rest of the buffers can be used for reading the response and, if needed, buffering part of the response to a temporary file. By default, size is limited by the s

Syntax: fastcgi_buffers number size; Default: fastcgi_buffers 8 4k|8k; Context: http, server, location Sets the number and size of the buffers used for reading a response from the FastCGI 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: fastcgi_buffering on | off; Default: fastcgi_buffering on; Context: http, server, location This directive appeared in version 1.5.6. Enables or disables buffering of responses from the FastCGI server. When buffering is enabled, nginx receives a response from the FastCGI server as soon as possible, saving it into the buffers set by the fastcgi_buffer_size and fastcgi_buffers directives. If the whole response does not fit into memory, a part of it can be saved to a tempora

Syntax: f4f; Default: — Context: location Turns on module processing in the surrounding location.

Syntax: fastcgi_bind address [transparent] | off; Default: — Context: http, server, location This directive appeared in version 0.8.22. Makes outgoing connections to a FastCGI 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 fastcgi_bind directive inherited from the previous configuration level, which allows the system to auto-as

Syntax: f4f_buffer_size size; Default: f4f_buffer_size 512k; Context: http, server, location Sets the size of the buffer used for reading the .f4x index file.

Syntax: etag on | off; Default: etag on; Context: http, server, location This directive appeared in version 1.3.3. Enables or disables automatic generation of the “ETag” response header field for static resources.

Syntax: events { ... } Default: — Context: main Provides the configuration file context in which the directives that affect connection processing are specified.
