# NAME

Cache::Memcached::Fast::Safe - Cache::Memcached::Fast with sanitizing keys and fork-safe

# SYNOPSIS

use Cache::Memcached::Fast::Safe;

my $memd = Cache::Memcached::Fast::Safe->new({
servers => [..]
});

#This module supports all method that Cache::Memcached::Fast has.

# DESCRIPTION

Cache::Memcached::Fast::Safe is subclass of [Cache::Memcached::Fast](https://metacpan.org/pod/Cache::Memcached::Fast).
Cache::Memcached::Fast::Safe sanitizes all requested keys for against
memcached injection problem. and call disconnect\_all automatically after fork
for fork-safe.

# ADDITIONAL METHOD

- get\_or\_set($key:Str, $callback:CodeRef \[,$expires:Num\])

Get a cache value for $key if it's already cached. If can not retrieve cache values, execute $callback and cache with $expires seconds.

$memcached->get_or_set('key:941',sub {
DB->retrieve(941)
},10);

callback can also return expires sec.

$memcached->get_or_set('key:941',sub {
my $val = DB->retrieve(941);
return ($val, 10)
});

# CUSTOMIZE Sanitizer

This module allow to change sanitizing behavior through $Cache::Memcached::Fast::Safe::SANITIZE\_METHOD.
Default sanitizer is

local $Cache::Memcached::Fast::Safe::SANITIZE_METHOD = sub {
my $key = shift;
$key = uri_escape($key,"\x00-\x20\x7f-\xff");
if ( length $key > 200 ) {
$key = sha1_hex($key);
}
$key;
};
