ngx_http_memcached_module

You can use this module to perform simple caching. There are plans to extend this module in the near future.

Example configuration

server {
    location / {
        set  $memcached_key  $uri;
        memcached_pass   name:11211;
        default_type     text/html;
        error_page       404 = /fallback;
    }

    location = /fallback {
        proxy_pass       backend;
    }
}

Variables

• $memcached_key

memcached_pass

syntax: memcached_pass [ name:port ]

default: none

context: http, server, location

The backend should set the data in memcached. The memcached key is "/uri?args".

Since 0.5.9 the memcached key is now in $memcached_key.

memcached_connect_timeout

syntax: memcached_connect_timeout [ time ]

default: 60000

context: http, server, location

The timeout for connecting to memcached, in milliseconds.

memcached_read_timeout

syntax: memcached_read_timeout [ time ]

default: 60000

context: http, server, location

The timeout for reading from memcached, in milliseconds.

memcached_send_timeout

syntax: memcached_send_timeout [ time ]

default: 60000

context: http, server, location

The timeout for sending to memcached, in milliseconds.

memcached_buffer_size

syntax: memcached_buffer_size [ size ]

default: see getpagesize(2)

context: http, server, location

The recv/send buffer size, in bytes.

memcached_next_upstream

syntax: memcached_next_upstream [ error | timeout | invalid_response | not_found | off ]

default: error timeout

context: http, server, location

Which failure conditions should cause the request to be forwarded to another upstream server? Applies only when the value in memcached_pass is an upstream with two or more servers.
