I just did a little test:
1. When redering page1 I'm setting a cookie. I'm also rendering a link
like:
SHtml.link("/page2", () => {
S.deleteCookie("marius")
}, Text("Got to /page1 and remove cookie"))
2. When I click the link page2 is rendered and in the HTTP header I am
seeing the cookie being sent down to browser with no value and the
expires is (1-1-1970 ....). Which is correct.
Br's,
Marius
