i like to know how WebSocket ,Server Sent Events,Forever Frame,long polling etc work to establish connection between server & client.

1) what does it mean Server Sent Events and how this works to establish connection between server & client.

2) what does it mean Forever Frame and how this works to establish connection between server & client.

3) what does it mean long polling and how this works to establish connection between server & client.

i read all about transport mechanish from this url http://www.asp.net/signalr/overview/signalr-20/getting-started-with-signalr-20/introduction-to-signalr

but from the above url things were not clear to me because they have not written in detail. so looking for in-depth knowledge about various type of SignalR transport mechanism & how they establish connection. thanks

  • You can also see Fiddler to trace what's being sent to the host. – Pawel May 01 '14 at 19:45
