[Cppcms-users] One SSE stream per session

[Christian G. <chr...@gm...>]

Hi all.

at the moment I am looking how to have one SSE stream per session. In
general I would put the SSE stream object into the session storage but
I am not sure how I could access it from other cppcms-apps.

Here is brief overview:

I have an SSE application mounted at /sse/

        booster::intrusive_ptr<SSE> sse = new SSE(srv);
        Configuration::instance()->sse = sse.get();
        srv.applications_pool().mount(sse, cppcms::mount_point("/sse(.*)", 1));

It is possible for all other cppcms apps running to send data via SSE
to the browser.

        Configuration::instance()->sse->enqueue("event", "data");


class SSE : public cppcms::application  {
public:
    SSE(cppcms::service &srv);

    void post();
    void get();
    void redirect();

    void enqueue(std::string const &event, std::string const &data);

private:
    booster::shared_ptr<sse::bounded_event_queue> stream_;
};



At the moment all clients are using the same SSE stream and this is a
no-go security wise.
So I want to extend my current approach to have multiple SSE streams -
for each session one.
As this "website" is used for embedded device configuration I think I
will not run into any
resource problems.

Or is there a better way to deliver each session their own data-packages only?

thanks
