Enabling OPTIONS method on Azure Cloud Service (to enable CORS)

OAuth2 redirection fails with CORS error
redirect,spring-security,oauth-2.0,cors,restful-authentication
After more investigation here are my conclusions. I'll start with #2 first. Yes, we probably took a wrong turn. Specifically, OAuth2 was designed for authorization, not authentication. (Though if we had been running our own OAuth2 server we might have gotten away with it.) Google supports authentication of course: see...
Am I able to retrieve a JIRA HTTP URL using a GET Request when I use CORS?

Spring security CSRF CORS
angularjs,rest,spring-security,cors,csrf
CSRF and CORS are not the same thing. You probably have the CORS part sorted now, but you need to add a CSRF token to any POST/PUT/DELETE requests. Spring Security sends the token in a header in the blog series you quoted and Angular picks it up from there (you...
Custom HTTP Header or cookies? how custom authentication/authorization helps in CSRF?
When authentication is based on cookie, every fired request from the client will be authenticated. Whether it is a "good" - intended by application, or "bad - as a result of CSRF attack.

Why does CORS allow sending data to any server?

The same-origin policy is designed purely to prevent one origin from reading resources from another origin.

Why do browsers have Same-Origin policies when workarounds like JSONP and CORS exist?
Your premise is incorrect. The Same Origin Policy says nothing about the ability of a web page to include resources on an external domain.

Accept is always simple, but Content-Type is only simple when it has the value application/x-www-form-urlencoded, multipart/form-data,...

I strongly suspect that the CORS is failing simply because of the HTTP 500 code returned from the server.

Why 500 is being returned, is dependent...
