Synopsis

You can use this module to perform simple caching.

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

Directives

memcached_pass

Syntax:	memcached_pass address
Default:
Context:	location if in location
Reference:	memcached_pass

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:	60s
Context:	http server location
Reference:	memcached_connect_timeout

The timeout for connecting to memcached.

memcached_read_timeout

Syntax:	memcached_read_timeout time
Default:	60s
Context:	http server location
Reference:	memcached_read_timeout

The timeout for reading from memcached.

memcached_send_timeout

Syntax:	memcached_send_timeout time
Default:	60s
Context:	http server location
Reference:	memcached_send_timeout

The timeout for sending to memcached.

memcached_buffer_size

Syntax:	memcached_buffer_size size
Default:	4k\|8k
Context:	http server location
Reference:	memcached_buffer_size

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
Reference:	memcached_next_upstream

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.

Variables

$memcached_key

The value of the memcached key.
