Abstract

A system and method for dynamically disabling partially streamed content may include a server receiving a request from a client. A session may be initiated or continued in response to the request. The server may begin to stream content to the client as a partial fulfillment of the request. While processing the request, the server may determine if the partially streamed content should be disabled. In response to determining that the partially streamed content should be disabled, the server may disable the partially streamed content without terminating the session. Disabling the partially streamed content may involve preventing the client from accessing content referenced by a hyperlink associated with the partially streamed content, or may involve the use of a controller located on the client to disable content streamed to the client.

Claims

1. A method, comprising:

processing a request from a client, wherein the request initiates or continues a session between a server and the client;

streaming out a portion of content from the server to the client as a partial fulfillment of the request;

while processing the request and subsequent to said streaming out the portion of content;

determining if access to the portion of content or additional content referenced by the portion of content should be disabled; and

in response to determining that access to the portion of content or the additional content should be disabled, disabling access to the respective content without terminating the session.

2. The method of claim 1, wherein said determining comprises detecting an occurrence of a security violation during said processing.

3. The method of claim 1, wherein said determining comprises detecting an occurrence of a process timeout.

4. The method of claim 1, wherein said disabling comprises preventing the client from accessing content referenced by a hyperlink associated with the portion of content streamed to the client.

5. The method of claim 4, wherein said preventing comprises:

maintaining a lookup table of all hyperlinks associated with the portion of content streamed to the client; and

invalidating the hyperlinks by modifying said lookup table to redirect the hyperlinks to an error message.

6. The method of claim 1, wherein said disabling comprises instructing a controller on the client to disable the portion of content received by the client.

7. The method of claim 6, wherein the controller is provided by the server and independent from any application running on the server.

8. The method of claim 6, wherein the controller is specific to an application running on the server.

9. The method of claim 6, wherein the controller is operable to disable access to the respective portion of content by prohibiting the respective portion of content from being copied or saved.

10. The method of claim 6, wherein the controller is provided by the client.

11. The method of claim 6, further comprising sending the controller to the client.

12. The method of claim 11, further comprising sending the controller to the client at the beginning of the session.

13. The method of claim 11, further comprising sending the controller to the client in response to said determining that access to the portion of content or the additional content should be disabled.

14. A system, comprising:

one or more processors; and

memory accessible by the one or more processors and configured to store program instructions executable by the one or more processors to implement a server configured to;

process a request from a client, wherein said request initiates or continues a session between the server and the client;

stream out a portion of content from the server to the client as a partial fulfillment of the request;

wherein the server comprises a content disabling mechanism configured to;

determine if access to the portion of content or additional content referenced by the portion of content should be disabled, wherein the content disabling mechanism is configured to perform said determining while processing said request and subsequent to said streaming out the portion of content; and

if access to the portion of content or the additional content should be disabled, disable access to the respective content without terminating said session.

15. The system of claim 14, wherein the content disabling mechanism is configured to determine that said access to the portion of content or the additional content should be disabled in response to an occurrence of a security violation during the processing of the request.

16. The system of claim 14, wherein the content disabling mechanism is configured to determine that said access to the portion of content or the additional content should be disabled in response to an occurrence of a process timeout.

17. The system of claim 14, wherein to disable access to the respective content, the content disabling mechanism is configured to prevent a user from accessing content referenced by a hyperlink associated with the portion of content streamed to the client.

18. The system of claim 17, wherein to prevent a user from accessing content referenced by a hyperlink, the content disabling mechanism is configured to maintain a lookup table of all hyperlinks associated with the portion of content streamed to the client, and invalidate one or more of the hyperlinks by modifying said lookup table to redirect the one or more hyperlinks to an error message.

19. The system of claim 14, further comprising a controller, wherein the controller is operable by the content disabling mechanism to prevent a user from accessing said hyperlink associated with the portion of content.

20. The system of claim 19, wherein the controller is provided by the server and independent from any application run on the server.

21. The system of claim 19, wherein the controller is specific to an application run by the server.

22. The system of claim 19, wherein the controller is operable by the content disabling mechanism to prohibit the portion of content from being copied or saved.

23. The system of claim 19, wherein the controller is built into the client.

24. The system of claim 19, wherein the server is further configured to send the controller to the client.

25. The system of claim 24, wherein the server is further configured to send the controller to the client at the beginning of the session.

26. The system of claim 24, wherein the server is further configured to send the controller to the client in response to determining that said portion of content should be invalidated.
