keep alive timeout doesn't add to response header

[yangmianmiao]

When set keep alive timeout by options.keepaliveTimeout_, I can't find keep-alive timeout in response header, is there any option need to set or could add this information to response header?

using namespace Pistache;

class HttpHandler : public Http::Handler {
public:
    HTTP_PROTOTYPE(HttpHandler)

    void onRequest(const Http::Request& request, Http::ResponseWriter response) override {
        // Extract general request information
        std::cout << "Request URL: " << request.resource() << std::endl;
        std::cout << "Request Method: " << request.method() << std::endl;
        std::cout << "Remote Address: " << request.remoteAddress().host() << std::endl;

        // Print request headers
        std::cout << "Request Headers:" << std::endl;
        for (const auto& header : request.headers()) {
            std::cout << header.first << ": " << header.second << std::endl;
        }

        // Set keep-alive timeout (in seconds)
        const int keepAliveTimeout = 5; // Example timeout value
        response.headers().add<Http::Header::KeepAlive>(std::to_string(keepAliveTimeout));

        // Create a response
        response.headers().add<Http::Header::ContentType>(MIME(Text, Plain));
        response.send(Http::Code::Ok, "Hello, World!");

        // Optionally add other response headers
        response.headers().add<Http::Header::AccessControlAllowOrigin>("*");
        response.headers().add<Http::Header::AccessControlAllowCredentials>("true");
        response.headers().add<Http::Header::ContentLength>(std::to_string(13)); // "Hello, World!" length
        response.headers().add<Http::Header::Date>(Http::Header::Date::formatNow());
    }
};

int main() {
    // Create an HTTP server
    Port port(9080);
    int threads = 2;

    auto opts = Http::Endpoint::options()
                    .threads(threads)
                    .keepAliveTimeout(std::chrono::seconds(5)); // Set keep-alive timeout here

    Http::Endpoint server(Address(Ipv4::any(), port));
    server.init(opts);

    // Set up the router
    Rest::Router router;
    Rest::Routes::Get(router, "/hello", Rest::Routes::bind(&HttpHandler::onRequest));

    server.setHandler(router.handler());

    // Start the server
    server.serve();
    return 0;
}

@ljluestc, I think he's asking about server side and not client side.

@yangmianmiao, you want to look at headerTimeout() and bodyTimeout().
