Abstract

Systems and methods for switching from a first Internet context to a second Internet context without process shutdown are described. Internet context data, such as cookies, history and user-defined data, is stored in containers unique to each user on a system. Internet content is stored in a common location so redundant downloaded information is not stored. Content information is found or stored by hashing a URL and indexing the memory location according to the resulting hash value. If content data is specific to a particular user, a hash is performed on a combination of the URL and an ordinal associated with the user'"'"'s unique identity to obtain a hash value unique to the user. The user-specific content is then stored and the memory location is indexed according to the unique hash value.

Claims

1. A method comprising:

receiving a request to switch from a first Internet context associated with a first user identity to a second Internet context associated with a second user identity;

storing the first Internet context in one or more containers associated with the first user identity;

setting one or more global pointers to reference the second Internet context located in one or more containers associated with the second user identity without requiring open processes associated with the first user identity to shut down;

determining if the second user identity has been utilized previously; and

if the second user identity has not been utilized previously, creating a new Internet context and setting one or more global pointers to reference the new Internet context stored in new containers and associating the new Internet context with the second user identity.

2. The method as recited in claim 1, wherein the first Internet context includes first Internet content stored in a memory location and identified in an index record, the index record being identified according to a hash value of a URL associated with the first Internet content.

3. The method as recited in claim 1, wherein the first Internet content is shared content.

4. The method as recited in claim 1, wherein the first Internet context includes first Internet content stored in a memory location and identified in an index record, the index record being identified according to a hash value of a URL associated with the first Internet content and a value uniquely associated with the first user identity.

5. The method as recited in claim 1, wherein the first Internet content is user-specific content.

6. The method as recited in claim 1, wherein the first user identity and the second user identity pertain to the same user.

7. The method as recited in claim 1, wherein the first user identity and the second user identity pertain to a different user.

8. A method comprising:

receiving a request to switch from a first Internet context associated with a first identity to a second Internet context associated with a second identity;

storing the first Internet context in one or more containers associated with the first identity;

setting one or more global pointers to reference the second Internet context located in one or more containers associated with the second identity without requiring open processes associated with the first identity to shut down;

determining if the second identity has been utilized previously; and

if the second identity has not been utilized previously1 creating a new Internet context and setting one or more global pointers to reference the new Internet context stored in new containers and associated the new Internet context with the second identity.

9. The method as recited in claim 8, wherein the first Internet context includes first Internet content stored in a memory location and identified in an index record, the index record being identified according to a hash value of a URL associated with the first Internet content.

10. The method as recited in claim 8, wherein the first Internet context includes first Internet content stored in a memory location and identified in an index record, the index record being identified according to a hash value of a URL associated with the first Internet content and a value uniquely associated with the first user identity.

11. The method as recited in claim 8, wherein the first user identity and the second user identity pertain to the same user.

12. The method as recited in claim 8, wherein the first user identity and the second user identity pertain to a different user.

13. A computer system, comprising:

a processor; and

memory configured to maintain one or more modules that are executable on the processor to;

receive a request to switch from a first Internet context associated with a first identity to a second Internet context associated with a second identity;

store the first Internet context in one or more containers associated with the first identity;

set one or more global pointers to reference the second Internet context located in one or more containers associated with the second identity without requiring open processes associated with the first identity to shut down;

determine if the second identity has been utilized previously; and

if the second identity has not been utilized previously, create a new Internet context and setting one or more global pointers to reference the new Internet context stored in new containers and associated the new Internet context with the second identity.
