# 対応方法 for Cross-Origin Session Cookies Not Being Sent After Upgrading to Django 3

<p>By default, Django3 sets the following in its settings:<br /><br /></p>
<pre><span class="pl-c1">SESSION_COOKIE_SAMESITE</span><span> </span><span class="pl-k">=</span><span>&nbsp;</span><span class="pl-c1">'Lax'</span></pre>
<p><span class="pl-c1"><br />This is the default configuration.</span></p>
<p><span class="pl-c1">To disable it:<br /><br /></span></p>
<pre><span class="pl-c1"><span class="pl-c1">SESSION_COOKIE_SAMESITE</span><span> </span><span class="pl-k">=</span><span> </span><span class="pl-c1">None</span></span></pre>
<p></p>
<p>After making this change, either log out or clear your cookies and log in again.</p>
<p>Note that this will weaken security.</p>
