How many instances of a Servlet filter will there be within the container

Supposed I have a LoginFilter, defined the usual way:
public class LoginFilter implements Filter,
Its executed for every URL that goes through the container (
, glassfish, etc.)
How many "LoginFilter" objects are in the VM? Just one? one per thread? perhaps a pool is kept by the container and managed by it?
Related: does the LoginFilter have to be thread safe?
