Hi
Thank you for reading my post
How I can cut the communication between client and server using a filter?
for example if user request header has no coockie, i do not allow the request to go to its endpoint and instead i generate some html and send it as response to the client without allowing the request to go in.

Thank you very much.

Write a filter that checks for the cookie and forwards to an error or login page if the cookie is not present.
If the cookie is present, call chain.doFilter.

Hi
Thank you for your reply.
I want the filter to write something in the output instead of redirecting to some other pages.
Is it possible?

Thanks
