NAME

Plack::Middleware::NeverExpire - set expiration headers far in the future

VERSION

version 1.006

SYNOPSIS

 # in app.psgi
 use Plack::Builder;
 
 builder {
     enable_if { $_[0]{'PATH_INFO'} =~ m!^/static/! } 'NeverExpire';
     $app;
 };

DESCRIPTION

This middleware adds headers to a response that allow proxies and browsers to cache them for an effectively unlimited time. It is meant to be used in conjunction with the Conditional middleware.

SEE ALSO

  • Plack::Middleware::Expires

    For most requests you want either immediate expiry with conditional GET, or indefinite caching, or on high-load websites maybe a very short expiry duration for certain URIs (on the order of minutes or seconds, just to keep them from getting hammered): fine-grained control is rarely needed. I wanted a really trivial middleware for when it's not, so I wrote NeverExpire.

    But when you need it, Expires will give you the precise control over expiry durations that NeverExpire doesn't.
