Pass (Send) Session variable from PHP to ASP.Net

Hello,

I am not sure why Chrome is not working with the session of php website.

I have a website that work with Microsoft Edge, and other brewers but not in Chrome.

I build the code in ASPX web application.

I load it to php with Iframe, and from there i will use the session to work and connect with the ASPX application.

Do you know how to fix it?

Please let me know if you need additional information.

Thank you
