short answer: no


long answer:

when connect webserver, web server responds sending piece of data. in case 'echo'. connection closed , history.

theoraticly possible send 1 piece of data multiple clients long connected webserver. i.e web browser shows 'loading page'

practically, not possible, because once connection closed, user has hit refresh button again connect server , fetch new data

i suggest read fantatic article give broad sense on how web servers work. http://computer.howstuffworks.com/web-server.htm
