Right now it's not possible because generally the opposite is expected, and haproxy only emits session cookies, not persistent cookies (which are often blocked by browsers). I don't think it should be too hard to add an "expires" option to the cookie. There is already a "domain". In the mean time, you might be able to perform an awfully dirty trick. If you set a domain to "mydomain.com;\ expires=XXX", it *might* work.

what is the main reason for the browser to restart ? Also, if you need to go back to the same server, I suppose you have a context there. Are you sure that the server cookie is persistent ? It sounds very strange to me as most often, application cookies are not persistent across brower restarts either.
