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: 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: proxy_max_temp_file_size size; Default: proxy_max_temp_file_size 1024m; Context: http, server, location When buffering of responses from the proxied server is enabled, and the whole response does not fit into the buffers set by the proxy_buffer_size and proxy_buffers directives, a part of the response can be saved to a temporary file. This directive sets the maximum size of the temporary file. The size of data written to the temporary file at a time is set by the proxy_temp

Syntax: proxy_limit_rate rate; Default: proxy_limit_rate 0; Context: http, server, location This directive appeared in version 1.7.7. Limits the speed of reading the response from the proxied 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 proxied server, the overall rate will be twice as much as the specified limit. The limitation works only if buf

Syntax: proxy_intercept_errors on | off; Default: proxy_intercept_errors off; Context: http, server, location Determines whether proxied responses with codes greater than or equal to 300 should be passed to a client or be intercepted and redirected to nginx for processing with the error_page directive.

Syntax: proxy_ignore_headers field ...; Default: — Context: http, server, location Disables processing of certain response header fields from the proxied server. The following fields can be ignored: “X-Accel-Redirect”, “X-Accel-Expires”, “X-Accel-Limit-Rate” (1.1.6), “X-Accel-Buffering” (1.1.6), “X-Accel-Charset” (1.1.6), “Expires”, “Cache-Control”, “Set-Cookie” (0.8.44), and “Vary” (1.7.7). If not disabled, processing of these header fields has the following effect: “X-Accel-E

Syntax: proxy_ignore_client_abort on | off; Default: proxy_ignore_client_abort off; Context: http, server, location Determines whether the connection with a proxied server should be closed when a client closes the connection without waiting for a response.

Syntax: proxy_http_version 1.0 | 1.1; Default: proxy_http_version 1.0; Context: http, server, location This directive appeared in version 1.1.4. Sets the HTTP protocol version for proxying. By default, version 1.0 is used. Version 1.1 is recommended for use with keepalive connections and NTLM authentication.

Syntax: proxy_hide_header field; Default: — Context: http, server, location By default, nginx does not pass the header fields “Date”, “Server”, “X-Pad”, and “X-Accel-...” from the response of a proxied server to a client. The proxy_hide_header directive sets additional fields that will not be passed. If, on the contrary, the passing of fields needs to be permitted, the proxy_pass_header directive can be used.

Syntax: proxy_headers_hash_max_size size; Default: proxy_headers_hash_max_size 512; Context: http, server, location Sets the maximum size of hash tables used by the proxy_hide_header and proxy_set_header directives. The details of setting up hash tables are provided in a separate document.
