Hi, I need to read a cookie from a different domain (it is not mine).
I known the name ok cookie.
When I create (write) a cookie, it is possible to set the name of domain:
cookie.setDomain(".example.com");
But It does'nt work for foreign domain just because security reasons, infact I
can not modify or create cookie for othen site, not own.
But I think it is possible to READ cookie from other site. Just the user set in
own browser settings "allow third party cookies".
How can do it in wicket?
I only know this instruction to read cookie, and in this I can not choose the
domain to use:
Cookie[] cookies = ((WebRequest)getRequestCycle().getRequest()).getCookies();
This is my test application:
