Hi All,

I have a Php website and it is hosted on the azure web app. It is also working fine. But when I am using it through the application gateway I am getting a CSRF token error on the login page. Can you help me please?

Thanks

@Mohit Kumar Sharma , I did test it locally and looks CSRF token has been transferred without any error.

My setup:

  1. Azure WebAPP with PHP (7.4)
  2. A sample PHP application with basic CSRF session module.
  3. Custom domain added to Azure WebApp with no binding.
  4. Azure Application gateway standard V2.

Generate-token.php
90401-generate-token.log

verifytoken.php
90259-verifytoken.log

Let us know what framework are you using here for implementing CSRF protection.
