Soumen Halder

Hello I am working with a web application on .net 4.7.2. where I am using to call cross site from my website. it was working before, but new a days it is not working due to samesite cookies policy. I have followed https://docs.microsoft.com/en-us/aspnet/samesite/system-web-samesite?source=docs and https://www.youtube.com/watch?v=OZv-C0pFh4M where I used cookieSameSite=None for my website, but nothing works. How to resolve?

add below code to your web.config
    "Add SameSite" preCondition="No SameSite">
      "RESPONSE_Set_Cookie" pattern=".*" negate="false" />
      "Rewrite" value="{R:0}; SameSite=strict" />




      "No SameSite">
        "{RESPONSE_Set_Cookie}" pattern="." />
        "{RESPONSE_Set_Cookie}" pattern="; SameSite=strict" negate="true" />
