This was the original rationale for creating cookies and in general storing web content on the client side.
First. let me help you clarify.

Cookies are generally not "queried" by a server. Cookies are sent to the server with each page (that belong to the same cookie domain) as part of the standard HTTP request.

If you open any web dev tool, like Google Chrome Web Dev Tools (but it is the same with each major browser), you will see the cookies are sent with each page, not requested by the server.

Sorry, I just wanted to be technically correct.
 
HTTP::Cookies::Microsoft(3)				User Contributed Perl Documentation			       HTTP::Cookies::Microsoft(3)

NAME
HTTP::Cookies::Microsoft - access to Microsoft cookies files SYNOPSIS
use LWP; use HTTP::Cookies::Microsoft; use Win32::TieRegistry(Delimiter => "/"); my $cookies_dir = $Registry-> {"CUser/Software/Microsoft/Windows/CurrentVersion/Explorer/Shell Folders/Cookies"}; $cookie_jar = HTTP::Cookies::Microsoft->new( file => "$cookies_dir\index.dat", 'delayload' => 1, ); my $browser = LWP::UserAgent->new; $browser->cookie_jar( $cookie_jar ); DESCRIPTION
This is a subclass of "HTTP::Cookies" which loads Microsoft Internet Explorer 5.x and 6.x for Windows (MSIE) cookie files. See the documentation for HTTP::Cookies. METHODS
The following methods are provided: $cookie_jar = HTTP::Cookies::Microsoft->new; The constructor takes hash style parameters. In addition to the regular HTTP::Cookies parameters, HTTP::Cookies::Microsoft recognizes the following: delayload: delay loading of cookie data until a request is actually made. This results in faster runtime unless you use most of the cookies since only the domain's cookie data is loaded on demand. CAVEATS
Please note that the code DOESN'T support saving to the MSIE cookie file format. AUTHOR
