Abstract

A method, apparatus, and computer instructions for managing caching of data by a browser. A request is received to retrieve a Web page. The request includes location information for the Web page. A determination is made as to whether a match is present in a data structure for the location information. In response to a match being present, the caching of data for the Web page is prevented or cached on a temporary basis.

Claims

1. A method in a data processing system for managing caching of data by a browser, the method comprising:

receiving a request to retrieve a Web page, wherein the request includes a location information for the Web page;

determining whether a match is present in a data structure for the location information; and

responsive to a match being present, managing caching of data for the Web page by preventing caching of data for the Web page or caching the data for the Web page on a temporary basis.

2. The method of claim 1 further comprising:

retrieving the Web page; and

displaying the Web page.

3. The method of claim 2, wherein the preventing step includes:

deleting data for the Web page from the data processing system after displaying the Web page.

4. The method of claim 1 further comprising:

responsive to a user input, adding new location information for the Web page to the data structure.

5. The method of claim 1, wherein the location information is a universal resource locator.

6. The method of claim 1, wherein the location information is a domain name.

7. The method of claim 1, wherein the data structure is a list of universal resource locators.

8. The method of claim 1, wherein caching the data on a temporary basis includes at least one of:

storing the data in a file that is overwritten with data for a second Web page when the second Web page is retrieved;

sending the data for the Web page to a “

/dev/null”

directory; and

writing the data to the file and subsequently erasing the file.

9. A data processing system for managing caching of data by a browser, the data processing system comprising:

receiving means for receiving a request to retrieve a Web page, wherein the request includes a location information for the Web page;

determining means for determining whether a match is present in a data structure for the location information; and

managing means, responsive to a match being present, for managing caching of data for the Web page by preventing caching of data for the Web page or caching the data for the Web page on a temporary basis.

10. The data processing system of claim 9 further comprising:

retrieving means for retrieving the Web page; and

displaying means for displaying the Web page.

11. The data processing system of claim 10, wherein the preventing means includes:

deleting means for deleting data for the Web page from the data processing system after displaying the Web page.

12. The data processing system of claim 9 further comprising:

adding means responsive to a user input, for adding new location information for the Web page to the data structure.

13. The data processing system of claim 9, wherein the location information is a universal resource locator.

14. The data processing system of claim 9, wherein the location information is a domain name.

15. The data processing system of claim 9, wherein the data structure is a list of universal resource locators.

16. The data processing system claim 9,. wherein caching means includes at least one of:

storing means for storing the data in a file that is overwritten with data for a second Web page when the second Web page is retrieved;

sending means for sending the data for the Web page to a “

/dev/null”

directory; and

writing means for writing the data to the file and for subsequently erasing the file.

17. A computer program product in a computer readable medium in a data processing system for managing caching of data by a browser, the computer program product comprising:

first instructions for receiving a request to retrieve a Web page, wherein the request includes a location information for the Web page;

second instructions for determining whether a match is present in a data structure for the location information; and

third instructions, responsive to a match being present, managing caching of data for the Web page by preventing caching of data for the Web page or caching the data for the Web page on a temporary basis.

18. The computer program product of claim 17 further comprising:

fourth instructions for retrieving the Web page; and

fifth instructions for displaying the Web page.

19. The computer program product of claim 17, wherein the third instructions includes:

sub-instructions for deleting data for the Web page from the data processing system after displaying the Web page.

20. The computer program product of claim 17 further comprising:

fourth instructions, responsive to a user input, for adding new location information for the Web page to the data structure.

21. The computer program product of claim 17, wherein the location information is a universal resource locator.

22. A data processing system comprising:

a bus system;

a memory connected to the bus system, wherein the memory includes a set of instructions; and

a processing unit connected to the bus system wherein the processing unit executes the set of instructions to receive a request to retrieve a Web page, wherein the request includes a location information for the Web page;

determine whether a match is present in a data structure for the location information;

manage caching of data for the Web page by preventing caching of data for the Web page or caching the data for the Web page on a temporary basis.
