I am doing SPA with a responsive router. With one route, I will need to show the authentication page from a third party through SAML 2.0 in an iframe. When the src frame loads, a third party sets a cookie in the iframe. However, Chrome does not send a third-party cookie in the iframe for the following HTTP requests in the same iframe.
Have you really appreciated whether someone can shed light on why Chrome behaves completely different than other browsers such as Firefox, Safari?
