    Not the app of course.It is done but the implemenetation of TCP/IP stack part of your OS

    In the web server <–> web browser environment , was apache programmed
    to send a SYN+ACK pachet upon the arrival or the SYN packet ?

    Application servers use underlying OS facilities for the network communication. The part you describe is completely done by the TCP/IP implementation of the OS

    I know how to send a raw packet

    Yes but when sending a raw packet you can only “form” the data in the frame which usually are not “visible”/accesible. You don’t define a flow or have any other control.
