Abstract

A computer-implemented process facilitates communication with an entity over a network. A static HTTP URL is associated with the entity. Communications information reflecting the entity'"'"'s current online presence including the entity'"'"'s dynamic session information as determined using the HTTP protocol is linked with the URL. Communication with the entity is facilitated using the URL and the communications information. The forms of communication facilitated include type chat/instant messaging, voice communication over a computer network, video communication over a computer network, voice communication from a computer network to a telephone network and two-way text messaging to Internet enabled wireless devices.

Claims

1. A method for providing online presence of a user using a client device on a computer network, the method comprising:

establishing and maintaining a socket and an HTTP connection between the client device and the chat server through a firewall;

adding a socket file descriptor of the HTTP connection for the user using the client device to a table of the chat server;

maintaining online presence of the user by determining the status of the socket of the HTTP connection for the user; and

wherein the socket being open serves to indicate the online presence of the user.

2. A method as in claim 1 further comprising closing said socket.

3. A method as in claim 2 further comprising ceasing said maintaining said record of said user'"'"'s online presence as a result of said socket being closed.

4. A method as in claim 2 further comprising receiving a message from said client device logging off said network.

5. A method as in claim 1 further comprising determining that said socket has been closed.

6. A method as in claim 5 further comprising ceasing said maintaining said record of said user'"'"'s online presence as a result of said socket being closed.

7. A method as in claim 1 further comprising failing to write to said socket.

8. A method as in claim 7 further comprising ceasing said maintaining said record of said user'"'"'s online presence as a result of said socket being closed.

9. A method as in claim 1 further comprising determining said socket is closed by failing to write to said socket.

10. A method as in claim 1 further comprising determining whether said socket is open.

11. A method as in claim 1 further comprising determining whether said socket is open by sending at least one byte of data to the socket.

12. A method as in claim 1 further comprising sending at least one byte of data to the socket.

13. A method as in claim 12 wherein said sending at least one byte of data to the socket further comprises sending a first byte of data at a first time and a second byte of data at a second time.

14. A method as in claim 12 wherein said sending at least one byte of data to the socket further comprises sending sequential bytes of data.

15. A method as in claim 14 wherein said sending sequential bytes of data further comprises sending single bytes of data in series.

16. A method as in claim 15 wherein each of said sending single bytes of data in series occurs at an interval.

17. A method as in claim 16 wherein said interval is a predetermined interval.

18. A method as in claim 17 wherein said predetermined interval is four seconds.

19. A method as in claim 17 wherein said predetermined interval is one minute.

20. A method as in claim 17 wherein said predetermined interval is two minutes.

21. A method as in claim 1 further comprising initiating said HTTP connection by the user using the client device.

22. A method as in claim 1 further comprising receiving said HTTP request and establishing said HTTP connection.

23. A method as in claim 1 further comprising establishing a record of said user'"'"'s online presence.

24. A method as in claim 1 wherein the HTTP request is a GET request.

25. A method as in of claim 1 wherein the HTTP request is a POST request.

26. A method as in claim 1 wherein said establishing and maintaining a socket and an HTTP connection further comprises establishing and maintaining a socket and an HTTP connection via an open socket in a non-blocking manner.

27. A method as in claim 26 further comprising adding said socket file descriptor to a socket database.

28. A method as in claim 1 wherein said establishing and maintaining a socket and an HTTP connection further comprises establishing and maintaining a socket and an HTTP connection via an open socket without creating a new thread.

29. A method as in claim 28 further comprising adding said socket file descriptor to a socket database.

30. A method as in claim 1 wherein said establishing and maintaining a socket and an HTTP connection further comprises establishing and maintaining a socket and an HTTP connection in a non-blocking manner without creating a new thread.

31. A method as in claim 1 further comprising having records of a plurality of users'"'"' online presence.

32. A method as in claim 1 further comprising adding said socket file descriptor to a socket database.

33. A method for providing online presence of a user using a client device on a computer network, the method comprising:

receiving an HTTP request initiated by the user using the client device at a chat server to establish an online presence for the user to communicate with other users;

establishing and maintaining a socket and an HTTP connection between the client device and the chat server through a firewall;

adding a socket file descriptor of the HTTP connection for the user using the client device to a table of the chat server;

maintaining online presence of the user by determining status of the socket of the HTTP connection for the user;

and wherein the socket being open serves to indicate the online presence of the user; and

,
