Abstract

System, method and program product determine whether a first web page returned to a web browser is a redirected web page. A dummy URL is created by appending one or more characters to a URL of the first web page. The one or more characters are chosen such that the dummy URL is likely to elicit a redirected web page. The request for the dummy URL is sent. A second web page is received in response to the request. The content of the second web page is compared to content of the first web page to determine if the first web page is a redirected web page. If the content of the second web page matches the content of the first web page, a record is made indicating that the first web page is a redirected web page.

Claims

1. A method for determining whether a first web page returned to a web browser is a redirected web page, said method comprising the steps of:

creating a dummy URL by appending one or more characters to a URL of said first web page, said one or more characters being chosen such that said dummy URL is likely to elicit a redirected web page;

sending a request for said dummy URL;

receiving a second web page in response to said request;

comparing content of said second web page to content of said first web page; and

making a record indicating that said first web page is a redirected web page if the content of said second web page matches said content of said first web page.

2. A method as set forth in claim 1 further comprising the steps of:

making a record indicating that said first web page was not determined to be a redirected web page if said content of said second web page does not match said content of said first web page.

3. A method as set forth in claim 1 wherein said one or more characters are chosen such that said dummy URL is not likely to match an application recognized by a same application that returned said second web page.

4. A method as set forth in claim 3 wherein the step of sending said request for said dummy URL comprises the step of sending said request for said dummy URL to a same application that returned said second web page.

5. A method as set forth in claim 1 wherein the comparing step comprises the step of comparing text of said second web page to text of said first web page.

6. A method as set forth in claim 5 wherein the comparing step further comprises the step of comparing graphics of said second web page to graphics of said first web page.

7. A method as set forth in claim 1 wherein the comparing step comprises the step of comparing graphics of said second web page to graphics of said first web page.

8. A method as set forth in claim 1 further comprising the step of:

scanning content of said first web page for a text phrase indicative of a redirected web page.

9. A method as set forth in claim 8 wherein said text phrase indicative of a redirected web page includes “

page not found”

or the like.

10. A system for determining whether a first web page returned to a web browser is a redirected web page, said system comprising:

a processor configured for;

creating a dummy URL by appending one or more characters to a URL of said first web page, said one or more characters being chosen such that said dummy URL is likely to elicit a redirected web page;

sending a request for said dummy URL;

receiving a second web page in response to said request;

comparing content of said second web page to content of said first web page; and

making a record indicating that said first web page is a redirected web page if the content of said second web page matches said content of said first web page.

11. A system as set forth in claim 10 further comprising:

wherein the processor is further configured for making a record indicating that said first web page was not determined to be a redirected web page if said content of said second web page does not match said content of said first web page.

12. A system as set forth in claim 10 wherein said one or more characters are chosen such that said dummy URL is not likely to match an application recognized by a same application that returned said second web page.

13. A system as set forth in claim 12 wherein the means for sending said request for said dummy URL comprises means for sending said request for said dummy URL to a same application that returned said second web page.

14. A system as set forth in claim 10 wherein the comparing means compares text of said second web page to text of said first web page.

15. A system as set forth in claim 14 wherein the comparing means also compares graphics of said second web page to graphics of said first web page.

16. A system as set forth in claim 10 further comprising:

means for scanning content of said first web page for a text phrase indicative of a redirected web page.

17. A computer program product for determining whether a first web page returned to a web browser is a redirected web page, said computer program product comprising program instructions stored on a computer readable medium, the program instructions comprising:

first program instructions to create a dummy URL by appending one or more characters to a URL of said first web page, said one or more characters being chosen such that said dummy URL is likely to elicit a redirected web page;

second program instructions to initiate sending of a request for said dummy URL;

third program instructions to fetch a second web page received in response to said request;

fourth program instructions to compare content of said second web page to content of said first web page; and

fifth program instructions to make a record indicating that said first web page is a redirected web page if the content of said second web page matches said content of said first web page.

18. A computer program product as set forth in claim 17, the program instructions further comprising:

sixth program instructions stored on the computer readable medium to make a record indicating that said first web page was not determined to be a redirected web page if said content of said second web page does not match said content of said first web page.

19. A computer program product as set forth in claim 17, the program instructions further comprising:

sixth program instructions stored on the computer readable medium to scan content of said first web page for a text phrase indicative of a redirected web page.

20. A computer program product as set forth in claim 19 wherein said text phrase indicative of a redirected web page includes “

page not found”
