4.7 <tt class="module">Cookie</tt> - HTTP State Management
</H1>
<A NAME="module-Cookie"></A>

<P>
The <tt class="module">Cookie</tt> module provides convenient ways for creating,
parsing, sending and receiving HTTP Cookies, as defined in the
specification published by Netscape.

<P>
<div class="note"><b class="label">Note:</b>
Even though there are official IETF RFC's describing HTTP State
  Management Mechanism using cookies, the de facto standard supported
  by most browsers is the original Netscape specification.
  Furthermore, true compliance with IETF standards is actually
  incompatible with many popular browsers, even those that claim to be
  RFC-compliant. Therefore, this module supports the current common
  practice, and is not fully RFC compliant.

<P>
More specifically, the biggest difference between Netscape and RFC cookies is 
  that RFC cookies are sent from the browser to the server along with their 
  attributes (like Path or Domain). The <tt class="module">Cookie</tt> module ignore those 
  incoming attributes, so all incoming cookies end up as Netscape-style cookies, 
  without any of their attributes defined.
