    How to set and get cookie in seam?

    Stateless Bean Novice

      Hi,
      I have one stateless bean in my app, and my scenario is:
      1. first time visit page set cookie with some value,
      2. second and more visits check if cookie exist and read it's value.

      I don't know where is my problem, each time I read only 2 cookies whitch aren't mine:
      1. session id cookie
      2. identity cookie
