I have two different web application. Services web app has REST Services defined. Client web app has JSP pages which makes call to REST services using Ajax to get the data and display in the UI. I want to implement OWASP CSRF Gaurd 3 for my REST services.
How can I get CSRF token value in Client application so that it can pass token value as header and rest services gets validated and executed?
Let me tell my architecture bit clearly.
Services Project - It is a spring/JPA project with REST web services defined. This project requires to be protected with CSRF. Its web context is /Services. So url might be in localhost like
Client Project - It is a JSP/Servlet project with jsp/html web pages. This project makes AJAX calls to Services project's REST Services to fetch the data and show it in UI. URL is like
Now my doubt is if I implement CSRF Guard in Services Project, Client project required CSRF token to call protected REST Services. How do I get this token value into Client projects jsp pages?
