ajax - Instant Transfer file between 2 browser clients via TCP -

-

is possible create website makes possible scenario:

user logs website, uploads file making direct tcp connection user b within same site @ same time downloading file. without passing file trough server.

how make user b listen through browser?

would violate "same origin policy"?

point use browser , no other software p2p clients.

is crazy idea possible?

i doubt webrtc covers need.

you have 2 issues:

  • b, if running web browser, cannot open port receive inbound connection
  • even if b able that, have face nat traversal issues.

the solution use/implement relay server:

  1. a opens outbound http/websocket connection relay server
  2. b opens outbound http/websocket connection relay server
  3. a sends data relay server on outbound channel (http post instance)
  4. b reads data relay server on response (to http instance)

easier said done.... (and yes feature of advanced p2p networks jxta, xmpp, skype..., , yes unfortunately need intermediate server)

check ice specification of 'how nat traversal'
