We have a Drupal website embedded to other websites.<br />
For example, the websites can embed our website in their website as following:<br />
&lt;iframe src=&quot;drupal_site_url&quot;&gt;&lt;/if<wbr />rame&gt;<br />
<br />
In this situation, Drupal site cookie becomes third-party cookie.<br />
<br />
Now more people block third-party cookie, so our Drupal site can not function inside<br />
the other websites this way.<br />
<br />
We have a control for the websites which embed our Drupal site.<br />
For example, we can modify the way like JavaScript, iframe.... to embed the Drupal site.<br />
Is there a method to make our Drupal site cookie become first-party cookie?

Drupal is an open-source content-management framework written in PHP used as a back-end framework for websites and is also used for knowledge management and business collaboration. The standard release of Drupal contains basic features common to content management systems, including user account registration and maintenance, menu management, RSS feeds, taxonomy, page layout customization, and system administration. Drupal runs on any computing platform that supports both a Web server capable of running PHP and a database to store content and configuration.
