How to set and get cookie in seam?
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
