Abstract

A method and system for injecting external content to a user'"'"'s client computer engaged in an interactive computer network session. A request for selected content from a user is intercepted and a decision is made whether to deliver external content to the user'"'"'s client computer in addition to the requested content. The method and system allows for local service providers such as ISPs to add their own content to sessions involving remote content suppliers.

Claims

1. A method for injecting external content into a computer network interactive session comprising the steps of:

a. receiving an electronic request from a client for selected content from a specified address location;

b. determining, based on predetermined criteria whether to deliver external content to said client;

c. upon determining to deliver said external content, transmitting said external content to said client and transmitting said request for selected content to said specified address location for response; and

d. upon determining not to deliver said external content, transmitting said request for selected content to said specified address location for response wherein said request for selected content is transmitted to said specified address location substantially unaltered.

2. The method for injecting external content as claimed in claim 1, wherein said predetermined criteria includes an addition policy.

3. The method for injecting external content as claimed in claim 2, wherein said addition policy uses at least one of a time interval, remote host information and type of requested content to determine whether to deliver external content to said client.

4. The method for injecting external content as claimed in claim 1, further comprising the step of storing said received electronic request in a storage device.

5. The method for injecting external content as claimed in claim 4, wherein said predetermined criteria includes whether an electronic request is similar to a stored electronic request.

6. The method for injecting external content as claimed in claim 1, further comprising the step of displaying said external content at said client until said selected content is delivered to said client.

7. The method for injecting external content as claimed in claim 1, wherein said client is a computer having a display device.

8. The method for injecting external content as claimed in claim 1, further comprising the step of displaying said external content at said client for a predetermined time.

9. The method for injecting external content as claimed in claim 1, further comprising the step of displaying said external content at said client along with said selected content.

10. The method for injecting external content as claimed in claim 1, wherein said electronic request received from said client is in the form of a packet.

11. The method for injecting external content as claimed in claim 10 wherein said packet includes at least one of a content type information and a specified address location information.

12. The method of claim 1 wherein said transmitting of said request for selected content to said specified address location is performed without waiting for a response of said client to said external content.

13. The method of claim 1 further comprising the step of:

e. upon receipt of a response to said request for selected content, transmitting said response to said client substantially unaltered.

14. A method of browsing in a computer network having at least one client computer electronically connectable to the Internet, said client computer being adapted to transmit requests for selected content to a specified address location and to allow downloading of requested selected content from said location on the Internet, comprising the steps of:

a. receiving a request for selected content from a client computer, said selected content being located at a specified address location;

b. intercepting said request for selected content upon delivery to said specified address location;

c. selectively delivering external content in addition to said selected content to said client computer for display; and

d. transmitting said request for said selected content to said specified address location wherein said request for selected content is transmitted to said specified address location substantially unaltered.

15. The method of browsing as claimed in claim 14, further comprising the step of receiving said selected content.

16. The method of browsing as claimed in claim 15, further comprising the step of delivering said selected content to said client computer.

17. The method of browsing as claimed in claim 14, wherein a computer network delay occurs over the Internet, said external content being delivered to said client computer during said delay.

18. The method of browsing as claimed in claim 14, wherein said external content is delivered to said client computer without changing said request for selected content.

19. The method of browsing as claimed in claim 18, wherein said external content is delivered to said client computer without changing said selected content.

20. The method of claim 14 wherein said transmitting of said request for selected content to said specified address location is performed without waiting for a response of said client to said external content.

21. The method of claim 14 further comprising the step of:

e. upon receipt of a response to said request for selected content, transmitting said response to said client substantially unaltered.

22. An automated system which allows for the delivery of external content to a web browser of a client coupled to the Internet through an ISP, comprising an ISP junction which receives a request for a web page directed to a specified address from said client, said ISP junction including a content injector, said content injector including access to an addition determining system which selectively determines when to deliver external content to said client based on predetermined criteria, and a transmission system which transmits said request for a web page to the specified address.

23. The automated system as claimed in claim 22, wherein said content injector includes a system administrator.

24. The automated system as claimed in claim 22, wherein said content injector is a computer.

25. The automated system as claimed in claim 22, wherein said content injector is an embedded CPU.

26. The automated system as claimed in claim 22, wherein said content injector further includes external content for delivery to said client computer.

27. The automated system as claimed in claim 22, wherein said addition determining system uses an addition policy to determine whether to deliver external content to said client.

28. The automated system as claimed in claim 27, wherein said addition policy uses at least one of a time interval, remote host information and type of requested content to determine whether to deliver external content to said client.

29. The automated system as claimed in claim 27, where said addition to determining system uses a central policy controller to configure said addition policy.

30. The automated system as claimed in claim 22, wherein said addition determining system is remotely located from said ISP.

31. The automated system as claimed in claim 22, wherein said content injector takes over control of a network session of said client over the Internet.

32. The automated system as claimed in claim 22, wherein said content injector further includes a transmission system for transmitting said external content to said client.

33. A system for injecting external content into a computer network interactive session, comprising a content injector including a processor, electronic storage and a gateway, wherein:

a. said storage including external content information;

b. said gateway including means for reading information packets transmitted from a client during a network interactive session, said packets including request information;
