How do I set up CSRF tokens in my web application?

To set up CSRF tokens, you need to generate a unique token for each user session and include it in your forms.

What steps do I need to take to generate the token?

You can use libraries like CSRF-Guard or implement it manually by creating a random string and storing it in the user's session.

How do I validate the token on form submission?

On form submission, compare the token sent with the form data to the one stored in the session. If they match, the request is valid.

What happens if the tokens don't match?

If the tokens don't match, you should reject the request and possibly return an error message indicating a CSRF attack.
