This article documents an issue that has been reported by some users working on Liferay Digital Experience Platform (DXP). It is a cookies issue that has been reported, and the issue arises when using certain versions of Internet Explorer behind a two-character domain (e.g., http://xx.yy) in the Liferay environment.
Resolution
To overcome this issue, you may configure the Liferay platform to explicitly set full hostnames on session cookies, and the cookie domain. Prior to making any adjustments to your environment, please ensure that your environment is backed up in the event that a rollback is required.
Please configure the environment's portal-ext.properties as follows, making any changes to the relevant properties based on your environment's specifications and needs:
session.cookie.use.full.hostname=true session.cookie.domain=<your hostname here>
