PERTAIN_TORootCause

you do not allow your site to be reached from browsers that refuse to serve unspecified servers — your API is on domain1 and I own domain2 where I want to request end points from your server. Tension: you exclude my domain2 from doing so on the client-side and you force such third-parties to send their requests from the server-side.

PERTAIN_TOProblem

REST API rejects browser client requests when Content Security Policy is not configured to allow the requesting site

PERTAIN_TOSolution

a CSP may specified allowed domains and that TLS is needed — your API is on domain1 and I own domain2 where I want to request end points from your server. Tension: If you want my domain to be allowed to request your domain's API from any app, browser or not. Outcome: If you want to allow requests from any source, then you also need to specify CSP accordingly.

PERTAIN_TOProblem

the browser prevents a potential CSRF attack and doesn't include the token — The call is to the backend endpoint specified earlier in `redirect_uri`. Tension: I need a browser to include the `ASP.NET_SessionId` cookie in the request. Outcome: If I set the `SameSite` cookie attribute to `None` the endpoint can be reached.

PERTAIN_TOProblem

Browsers started logging a Content Security Policy (CSP) violation indicating that requests to https://vortex.data.microsoft.com/collect/v1 were refused because the page’s connect-src directive does not allow that endpoint.

PERTAIN_TOSolution

Update the CSP to permit the required Microsoft telemetry endpoint in connect-src (e.g., add https://vortex.data.microsoft.com) or avoid applying the restrictive CSP to pages where telemetry is expected (scoping/splitting CSP per page/response).

PERTAIN_TOProblem

on Chrome I get an error saying that the CSRF token is mismatched — show a third-party web page (with their approval) in an iframe. Tension: This site has a different domain to my parent site. Outcome: The site displays fine on firefox.

PERTAIN_TOSolution

set the same site value to none — Setting samesite on server config level. Tension: Wildfly( didn't work for me. Outcome: I added the following filter to add the samesite value.
