Cookie + redirect on another host

Question

Hi all,
I have created a cookie with some informations, and put it in the response. Then, I have to redirect to an url (http://etc...) with is not on the same server ( I can't do forward("/webapp/...") )
But when i do a response.sendRedirect("http://...), my Cookie is lost.
How could I keep that Cookie ? Can i force the Cookie to be written on the other server before i do the sendRedirect ?
Thanks.

By default, browsers only send cookies back to the site they came from originally (actually to any any site within the same DNS domain), so if the site you're redirecting to is in another DNS domain, you're out of luck.
If you're trying to redirect to another server, make sure of the following:
- you've called setDomain on the Cookie, with the corredct domain info
- you've called setPath on the Cookie
If it still doesn't work, you may try the following trick:
- instead of a sendRedirect, just return an ordinary html document
- in the head part of the html document, include a header like this:
<meta http-equiv="Refresh" content="3;URL=http://www.some.org/some.html">
This makes the browser redirect to the specified url after 3 seconds (feel fre to specify your own number of seconds...)
