 The form POST request will fail with HTTP status `400` if the filter finds the hidden CSRF form field is missing, the CSRF cookie is missing, or if the CSRF form field and CSRF cookie values do not match.
 
-At this stage no additional configuration is needed - by default the CSRF form field and cookie name will be set to `csrf_token`, and the filter will verify the token. But lets change these names:

-Note that the CSRF filter has to read the input stream in order to verify the token and then re-create the stream for the application code to read it as well. The filter performs this work on an event loop thread so for small form payloads such as the one shown in the example above it will have negligible peformance side-effects. However if you deal with large form payloads then it is recommended to compare the CSRF form field and cookie values in the application code:
