Hello all!
I used to use expr for doing simple mathematics, but has a main advantage and a main disadvantage:

NAME
Plack::Middleware::Deflater - Compress response body with Gzip or Deflate
SYNOPSIS
use Plack::Builder;
builder {
enable sub {
my $app = shift;
sub {
my $env = shift;
my $ua = $env->{HTTP_USER_AGENT} || '';
# Netscape has some problem
$env->{"psgix.compress-only-text/html"} = 1 if $ua =~ m!^Mozilla/4!;
# Netscape 4.06-4.08 have some more problems
$env->{"psgix.no-compress"} = 1 if $ua =~ m!^Mozilla/4.0[678]!;
# MSIE (7|8) masquerades as Netscape, but it is fine
if ( $ua =~ m!MSIE (?:7|8)! ) {
$env->{"psgix.no-compress"} = 0;
$env->{"psgix.compress-only-text/html"} = 0;
}
$app->($env);
}
};
enable "Deflater",
content_type => ['text/css','text/html','text/javascript','application/javascript'],
vary_user_agent => 1;
sub { [200,['Content-Type','text/html'],["OK"]] }
};
DESCRIPTION
Plack::Middleware::Deflater is a middleware to encode your response body in gzip or deflate, based on "Accept-Encoding" HTTP request
header. It would save the bandwidth a little bit but should increase the Plack server load, so ideally you should handle this on the
frontend reverse proxy servers.
This middleware removes "Content-Length" and streams encoded content, which means the server should support HTTP/1.1 chunked response or
downgrade to HTTP/1.0 and closes the connection.
CONFIGURATIONS
content_type
content_type => 'text/html',
content_type => [ 'text/html', 'text/css', 'text/javascript', 'application/javascript', 'application/x-javascript' ]
Content-Type header to apply deflater. if content-type is not defined, Deflater will try to deflate all contents.
vary_user_agent
vary_user_agent => 1
Add "User-Agent" to Vary header.
ENVIRONMENT VALUE
psgix.no-compress
Do not apply deflater
psgix.compress-only-text/html
Apply deflater only if content_type is "text/html"
