Hello ,
I want to learn the technique (or some keywords to start searching) of a chat application which doesnt request and get response every second . For example https://www.jabbify.com/ (also faceboox chat application works like that ) has a chat box right down corner of the page .I have examined it with fiddler and it seems that sending request to the server is made when I send a message but no activity is seen every second . It seems that the chat box is listening server and when sth. is sent to the user an activity fires at server side .
So how it is done . Some keywords may be enough for me to research about the technology .
Thanks ...
