delete cookie from request ?

[Miran Cvenkel]

I have a standard func that deletes cookie:

myCookie.setMaxAge(0)
response.addCookie(myCookie);

But this is done only when response arives to client.
I need to read request before that and read from it, that cookie does not exist any more.
So I need also to delete cookie from request.

How to do that ?

If I understand your question correctly, Cookies are created in server side and stored in client side. if cookie you have stored in client side expired, then it wont come with request. so no need to delete the cookie from request.

so, I have a 'samplepage 'with

<%if (cookie) {%>
< a href = "samplepage?p1= logoff" > logoff</a>
<%}%>

1.that jumps to server
2.there I delete cookie server side , but that i not deleted until whole thing comes back to client,
that is, whole page is loaded, then on the end cookie is deleted, that is how I see it.
3. hence logoff link is stil visible, when I come back to same page,allthough it should not be
4. proof:click browser refresh, and logoff is gone

Edit: upper thing might be wrong, but anyway,
If at the time beeing at server side I 'delete' cookie from response, I would like to read somewhere that it is deleted,
the best thing seems to be to check current request, which still has it.

Make a two phase logout.

From client you call "logout".
Server does what it should and return you to a "/logoutevent.jsp" that clears the cookies and redirect you to the next page.
