[Renjith CJ]

Please Help...
I'm new in software field. I am create an application in angular js, and cppcms used for the back end.
when tried to check session().is_set() after login page it shows 0. sample code is given below.

This is my sample code,

class hello : public cppcms::application {
public:
hello(cppcms::service &srv) :
cppcms::application(srv)
{
dispatcher().assign("/login.php", &hello::login, this);
dispatcher().assign("/mango.php", &hello::mango, this);
dispatcher().assign("/apple.php", &hello::apple, this);
}
void login()
{
if (request().request_method() == "POST")
{
........
.......
........
session()["name"]=username;

        std::cout << session().is_set("name") << std::endl;  //it shows 1
    }
}
void mango()
{
    std::cout << session().is_set("name") << std::endl;  //it shows 0
}
void apple()
{
    std::cout << session().is_set("name") << std::endl;  //it shows 0
}

};

int main(int argc, char ** argv)
{
try {
cppcms::service srv(argc, argv);
srv.applications_pool().mount(
cppcms::applications_factory<hello>()
);
srv.run();
}
catch (std::exception const &e) {
std::cerr << e.what() << std::endl;
}
}

This is config.js file,

{
"service" : {
"api" : "http",
"port" : 8080
},
"http" : {
"script" : "/hello"
},
"session" : {
"expire" : "fixed",
"timeout" : 604800,
"location" : "client",
"client" : {
"hmac" : "sha1",
"hmac_key" : "3891bbf7f845fd4277008a63d72640fc13bb9a31"
}
},
}

From your partial "sample" it seems that modifing session is the last thing you do.

You can't change session values once output was generated:

once you call response().out() - all headers (including session data) are generated.
