My codes looks like so:

kaimei_web_site::kaimei_web_site(cppcms::service
&srv):cppcms::application(srv){
    //web page
    dispatcher().assign("/welcome" , &kaimei_web_site::welcome , this , 1);
//first page
    dispatcher().assign("/register" , &kaimei_web_site::register_client ,
this , 2); //register a new account on this page
....
    //restful web method called by Javascript form client-side
    dispatcher().assign("/send_email" , &kaimei_web_site::save_email , this
, 7);
    dispatcher().assign("/create_account?(.+)" ,
&kaimei_web_site::create_account , this , 8);
....

}


//render the register html page for user
void kaimei_web_site::register_client(std::string url){
    BOOSTER_INFO("kaimei_web_site") << "enter register_client function";
    init_session();

    string language = this->session().get("language");
    language_cache& cache = app_singleton_holder::Instance().cache();
    content::welcome_content content =
cache.get(language).clone_welcome_content();
    configuration& config = app_singleton_holder::Instance().config();
    content.base_uri=config.base_uri;
    content.jsonp= config.jsonp;
    render("create_account","create_account_view",content);
}


void kaimei_web_site::create_account(std::string str){
    try{
init_session();
 string email = request().post().find("email")->second;
string pwd = request().post().find("pwd")->second;
 user_manager::create_account(email,pwd);
string language = this->session().get("language");

shared_ptr<web_user> user = user_manager::login(email,pwd);
if(user){
  BOOSTER_INFO("kaimei_web_site") << "login succeeded";
  this->session()["email"]=user->email;
  this->session()["user_id"]=user->oid;
  configuration& config = app_singleton_holder::Instance().config();
  response().set_redirect_header(config.jsonp + "/user_home");   //I try to
redirect to new page but failed
 }else{
  kaimei::response res;
  res.message="Login failed!";
  res.status=kaimei::response::LOGIN_ERROR;
  response().out()<<cppcms::json::value(res);
}
    }catch(std::exception &ex){
kaimei::response res;
res.message=ex.what();
 res.status=kaimei::response::CREATE_ACCOUNT_ERROR;
response().out()<<cppcms::json::value(res);
    }

}

the real value of config.jsonp
(gdb) p config.jsonp
$1 = {static npos = <optimized out>, _M_dataplus = {<std::allocator<char>>
= {<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data
fields>}, _M_p = 0x80c6e24 "http://localhost:8081/kaimei"}}


 3. Small example that reproduces the problem.
