I am integrating a single-page application in Dynamics 365 using Channel Integration Framework. I am using Google Chrome as browser. My application also used cookies to maintain user sessions.
However, Google has announced that from Q1 2024 here: Prepare for phasing out third-party cookies - Chrome for Developers
That they will be phasing out support for third-party cookies. My application behaves as third-party in Dynamics 365 which cannot function without cookies.
I have simulated the phasing out of third-party cookies by browsing to the following URL in Chrome:
chrome://flags/#test-third-party-cookie-phaseout
And set the Test Third Party Cookie Phaseout to Enabled but my application is not displaying.
I have tried their solution which recommends using CHIPS (Cookies Having Independent Partitioned State) by adding the /Partitioned/ option in the /Set-Cookies/ header but it does not work.
Here is the code I am using in ASP.NET Web API:
string setCookieHeader = Response.Headers[/Set-Cookie/]; if (!string.IsNullOrEmpty(setCookieHeader)) { setCookieHeader += /;Partitioned/; Response.Headers[/Set-Cookie/] = setCookieHeader; }
With third-party phasing out simulated, the above code should have worked.
Is this because Dynamics 365 is loading my application in an ?
I do not have control over the creation of since it is in Dynamics 365. What is the solution to this problem since the /Partitioned/ attribute is not working in Dynamics 365 either?
