IS there virus software for unix? I worked in a Solaris environment and dont remember having anything. I also ask because the current enviroment i am working on is Microsoft and they argue that they do not use unix because of virus detection. Any input would be greatly appreciated. (1 Reply)

plack::middleware::conditional
Plack::Middleware::Conditional(3pm) User Contributed Perl Documentation Plack::Middleware::Conditional(3pm)NAME
Plack::Middleware::Conditional - Conditional wrapper for Plack middleware
SYNOPSIS
use Plack::Builder;
builder {
enable_if { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' } 'StackTrace', force => 1;
$app;
};
# or using the OO interface:
$app = Plack::Middleware::Conditional->wrap(
$app,
condition => sub { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' },
builder => sub { Plack::Middleware::StackTrace->wrap($_[0], force => 1) },
);
DESCRIPTION
Plack::Middleware::Conditional is a piece of meta-middleware, to run a specific middleware component under runtime conditions. The goal of
this middleware is to avoid baking runtime configuration options in individual middleware components, and rather share them as another
middleware component.
EXAMPLES
Note that some of the middleware component names are just made up for the explanation and might not exist.
# Minify JavaScript if the browser is Firefox
enable_if { $_[0]->{HTTP_USER_AGENT} =~ /Firefox/ } 'JavaScriptMinifier';
# Enable Stacktrace when being accessed from the local network
enable_if { $_[0]->{REMOTE_ADDR} =~ /^10.0.1.*/ } 'StackTrace';
# Work with other conditional setter middleware:
# Transcode Jpeg on the fly for mobile clients
builder {
enable 'MobileDetector';
enable_if { $_[0]->{'plack.mobile_detected'} }
'TranscodeJpeg', max_size => 30_000;
$app;
};
Note that in the last example MobileDetector should come first because the conditional check runs in pre-run conditions, which is from
outer to inner: that is, from the top to the bottom in the Builder DSL code.
