Yes. This is the question I asked in SO:
http://stackoverflow.com/questions/38245088/open-a-download-window-and-send-cookies-without-navigating-away-from-the-page

window.location.replace() is called after HTML <input> is clicked
roughly looks like this:

i_am_clicked:function(e){
  window.location.replace("/special");
}

It is not called from AJAX.

Server log shows that it does receives the cookie that comes with
prefix. That cookie string is exactly the same as that hold by browsers.

The request from client in question has one thing different from others
- it is initiated by javascript call window.location.replace() or its
flavors, while other "valid" requests are initiated by human mouse
clicks.

I think that server confirms that too according to this server code:

for(auto const &c : request().cookies())
BOOSTER_DEBUG("COOKIES") << c.first << ":" << c.second.path() << "==>"
<< c.second.value();

Cookie value associated with key "prefix" is written to log.
