net/http: SetCookie 'Max-Age' field can not be empty

[yandd]

I need to set a cookie which expired after closing browser.
Chrome browser just work well when 'Max-Age' field is empty.
So I think "http.SetCookie" function must support 'Max-Age' field to keep empty.

@nigeltao, are you still the cookie monster?

[nigeltao]

I'm a little confused as to what the original post is asking for. http.SetCookie takes a *Cookie as an argument, and the Cookie struct type has a MaxAge field.

https://golang.org/pkg/net/http/#Cookie says:

    // MaxAge=0 means no 'Max-Age' attribute specified.
    // MaxAge<0 means delete cookie now, equivalently 'Max-Age: 0'
    // MaxAge>0 means Max-Age attribute present and given in seconds
    MaxAge   int

Do either of the first two do what you want?

http://tools.ietf.org/html/rfc6265#section-4.1.2.2
“If a cookie has neither the Max-Age nor the Expires
attribute, the user agent will retain the cookie until "the current
session is over" (as defined by the user agent).”
