Submiting form do not return every header/cookie

[MikhailKlemin]

Hello!
I am submitting a login form and it's working OK, I logged in, but I do not see all response headers (which I can get via say POSTMAN) especially concerning is JSESSIONID. May be there some setting I missing...

bow := surf.NewBrowser()
/*
Submiting form here
*/

//Reading Headers and Cookies
for k, c := range bow.ResponseHeaders() {
    fmt.Println(k, "\t", c)
}

for k, c := range bow.SiteCookies() {
    fmt.Println(k, "\t", c)
}
