Hi,
If you can read the cookies from the jsp/servlets you've added from javascript,
there may be some reasons.
I think,
1. The path of Cookie : if you didn't set the path of cookies, then you could only see
the cookies
in the same path the cookie-writing page resided in.
2. The order of javascript and JSP in one page : JSP is executed first, then
javascript executed with generated HTML.
3. Browser BUGs : ...
4. The JSP/Servlet engine BUGs : ...
The thoughts of mine are so incomplete...

Subject: RE: Writing cookie in jsp
Hi,
sorry to join in late, but as i went thro' the mails, i found i could
contribute a similar problem i had,
I am doing some assumptions,
you are mixing JSP and javascript cookies, if i am wrong pls correct me....
"this will not work........"
why, i dont know, i have had an experiance once, that when i try to add
cookies from javascript, i cannot read it from the jsp/servlets api....
is this a drawback or a security feature is open for discussion, but when
you set the cookie in a javascript, the cookie cannot be read in the
JSP....????????
well you can actually set(response) the cookie in jsp itself, and
read(request) from it.
so if you can actually clear me up on the problem at hand maybe i can help
out,
