NAME

Dancer::Plugin::Memcached - Cache response content to memcached

CONTENTS

SYNOPSIS

This plugin gives Dancer the ability to get and store page content in a memcached server, which in specific configurations could give a performance boost - particulary on GET requests that incur significant database calls.

In your configuration, a list of servers with port numbers needs to be defined.



    plugins:
        Memcached:
        servers:
            - "10.0.0.15:11211"
        - "10.0.0.17:11211"
            default_timeout: 86400



The default_timeout specifies an fallback time for keys to expire from the cache. If this value is less than 60*60*24*30 (30 days), time is assumed to be seconds after the key was stored. If larger, it’s considered an absolute Unix time.

In your package:



    package MyWebService;
    use Dancer;
    use Dancer::Plugin::Memcached;

    get / sub => {
        # Do your logic here
    ...
        memcached_set template($foo);
    };



This plugin will use the PATH_INFO environment variable to store as the key so routes that make use of parameters in the form of /foo/:bar will be cached, but GET/POST variables will not.

KEYWORDS

    memcached_check

Will check for any route and return the page stored in memcached where available.

    memcached_set($content, [$expiration])

For any given content, set and return the content. Expiration time for the set can optionally be set.

    memcached_get($key)

Grab a specified key. Returns false if the key is not found.

memcached_store($key, CW$content, [$expiration])

This keyword is identical to memcached_set with the exception that you can set any key name.
