Loss of cookie in an iframe

[RD_9924398]

Hello,

I develop a thingworx application and our application is in a site that publishes us as an iframe.

But in this way, the cookies do not work anymore. Indeed, the domain name on my browser is no longer the one of the Thingworx application. And I have the impression that it does not fit anymore.

Is it possible to configure the cookie domain name so that it works as an iframe?

Thank you for your help.

Hi @RD_9924398 

You might need

SameSite = None

parameter in order to pass cookies through iFrames.
