<p>The <strong>CookieProcessor</strong> element represents the component that
parses received cookie headers into <code>jakarta.servlet.http.Cookie</code>
objects accessible through <code>HttpServletRequest.getCookies()</code> and
converts <code>jakarta.servlet.http.Cookie</code> objects added to the response
through <code>HttpServletResponse.addCookie()</code> to the HTTP headers
returned to the client.</p>
<p>A CookieProcessor element MAY be nested inside a
<a href="context.html">Context</a> component. If it is not included, a default
implementation will be created automatically.</p>
</div><h3 id="Attributes">Attributes</h3><div class="text">

Description

<p>The standard implementation of <strong>CookieProcessor</strong> is
<code>org.apache.tomcat.util.http.Rfc6265CookieProcessor</code>.</p>
<p>This cookie processor is based on RFC6265 with the following changes to
support better interoperability:</p>
<ul>
<li>Values 0x80 to 0xFF are permitted in cookie-octet to support the use
of UTF-8 in cookie values as used by HTML 5.</li>
<li>For cookies without a value, the '=' is not required after the name as
some browsers do not sent it.</li>
</ul>
<p>The RFC 6265 cookie processor is generally more lenient than the legacy
cookie parser. In particular:</p>
<ul>
<li>The '<code>=</code>' and '<code>/</code>' characters are always
permitted in a cookie value.</li>
<li>Name only cookies are always permitted.</li>
<li>The cookie header is always preserved.</li>
</ul>
<p>The <strong>RFC 6265 Cookie Processor</strong> supports the following
additional attributes.</p>
<table class="defaultTable"><tr><th style="width: 15%;">
Attribute
</th><th style="width: 85%;">
Description
</th></tr><tr id="Attributes_Standard Implementation_cookiesWithoutEquals"><td><code class="attributeName">cookiesWithoutEquals</code></td><td>
<p>Determines how a cookie received from a user agent should be
interpreted when the name value pair does not contain an equals sign.
The default value is <code>name</code> which means that the cookie will
be treated as a cookie with a name but no value. The other option is
<code>ignore</code> which means the cookie will be ignored. From Tomcat
12 onwards the default will be <code>ignore</code>.</p>
</td></tr><tr id="Attributes_Standard Implementation_partitioned"><td><code class="attributeName">partitioned</code></td><td>
<p>Should the Partitioned flag be set on cookies? Defaults to <code>false</code>.</p>
<p>Note: The name of the attribute used to indicate a partitioned cookie as part of
<a href="https://developers.google.com/privacy-sandbox/3pcd#partitioned">CHIPS</a> is not defined by an RFC and
may change in a non-backwards compatible way once equivalent functionality is included in an RFC.</p>
</td></tr><tr id="Attributes_Standard Implementation_sameSiteCookies"><td><code class="attributeName">sameSiteCookies</code></td><td>
<p>Enables setting same-site cookie attribute.</p>
<p>If value is <code>unset</code> then the same-site cookie attribute
won't be set. This is the default value.</p>
<p>If value is <code>none</code> then the same-site cookie attribute
will be set and the cookie will always be sent in cross-site requests.</p>
<p>If value is <code>lax</code> then the browser only sends the cookie
in same-site requests and cross-site top level GET requests.</p>
<p>If value is <code>strict</code> then the browser prevents sending the
cookie in any cross-site request.</p>
