Well I tried to recreate the problem but it works as intended in my short example. I really don't know where could be the problem since I am doing it exactly the same way in my example as in my application. Maybe the problem is in the std::string, because when I use std::string.replace() to replace some characters in the URL then it works fine. But when I dont use it and append the URL to "success:" message right away, then it does not work. So maybe std::string.replace() somehow fixes the string when it rearranges it. The first problem with "login" was because I wasn't using size() in string constructor.
