Abstract

A method for enabling a server to maintain an accurate count of web-page views. The server maintains a counter that records the number of times the page is accessed due to automatic browser refreshes, and a counter that records the number of times the page is accessed otherwise. A browser accesses the URL of the web page and records a timestamp. When the browser next accesses the page, it determines the present time, and subtracts the timestamp from the present time. The browser then compares the difference with bounds that reflect a window of tolerance about an expected content-update period of the web page. If the difference is within the bounds, the browser instructs the server to advance the automatic-refresh counter; otherwise, the server advances the page-hit counter.

Claims

1. A method for providing information that enables a server to record data indicative of the number of times a web page is accessed under deliberate control of a user, said method comprising:

accessing the web page by a client, using a web browser, from the server that has transmitted the web page across a communication network to the client, wherein the server comprises two counters whose content is indicative of the number of times the web page has been acccssed while not being automatically refreshed;

recording a timestamp indicating an approximate time of accessing the web page by the client;

determining a content-update period at which the web page is periodically updated by the server;

configuring the browser to refresh the web page automatically according to the content-update period;

after said accessing, re-accessing the web page;

determining an approximate time of re-accessing the web page;

analyzing the timestamp, the approximate time re-accessing the web page, and the content-update period;

ascertaining, responsive to an outcome of said analyzing, whether said re-accessing the web page is or is not indicative of an automatic refresh by the web browser; and

instructing the server to advance at least one counter of the two counters in a manner that reflects an outcome of said ascertaining, wherein after advancing the at least one counter in said manner the server is adapted to determine from the content of the two counters the number of times the web page has been accessed while not being automatically refreshed,

wherein said recording the timestamp, said determining the content-update period, said configuring the browser, said re-accessing the web page, said determining the approximate time of re-accessing the web page, said analyzing, said ascertaining, and said instructing are performed by the client.

2. The method of claim 1, wherein said ascertaining has ascertained that the re-accessing the web page is indicative of said automatic refresh by the web browser.

3. The method of claim 1, wherein said ascertaining has ascertained that the re-accessing the web page is not indicative of said automatic refresh by the web browser.

4. The method of claim 1, wherein the two counters consist of a hit-rate counter and an automatic-refresh counter, wherein the hit-rate counter records the number of times the web page has been accessed while not being automatically refreshed, and wherein the automatic-refresh counter records the number of times the web page has been accessed while being automatically refreshed.

5. The method of claim 4, wherein said ascertaining has ascertained that the re-accessing the web page is not indicative of said automatic refresh by the web browser, and wherein during said instructing the at least one counter consists of the hit-rate counter.

6. The method of claim 4, wherein said ascertaining has ascertained that the re-accessing the web page is indicative of said automatic refresh by the web browser, and wherein during said instructing the at least one counter consists of the automatic-refresh counter.

7. The method of claim 1, wherein the two counters consist of a total access counter and an automatic-refresh counter, wherein the total access counter records the total number of times the web page has been accessed, and wherein the automatic-refresh counter records the number of times the web page has been accessed while being automatically refreshed.

8. The method of claim 7, wherein said ascertaining has ascertained that the re-accessing the web page is not indicative of said automatic refresh by the web browser, and wherein during said instructing the at least one counter consists of the total access counter.

9. The method of claim 7, wherein said ascertaining has ascertained that the re-accessing the web page is indicative of said automatic refresh by the web browser, and wherein during said instructing the at least one counter consists of the total access counter and the automatic-refresh counter.

10. The method of claim 1, wherein the two counters consist of a total access counter and a hit-rate counter, wherein the total access counter records the total number of times the web page has been accessed, and wherein the hit-rate counter records the number of times the web page has been accessed while not being automatically refreshed.

11. The method of claim 10, wherein said ascertaining has ascertained that the re-accessing the web page is not indicative of said automatic refresh by the web browser, and wherein during said instructing the at least one counter consists of the total access counter and the hit rate counter.

12. The method of claim 10, wherein said ascertaining has ascertained that the re-accessing the web page is indicative of said automatic refresh by the web browser, and wherein during said instructing the at least one counter consists of the total access counter.

13. The method of claim 1, wherein said analyzing comprises:

computing a difference between the approximate time of re-accessing the web page and the timestamp;

deciding whether the difference is within a specified tolerance interval, wherein the specified tolerance interval comprises the content-update period;

if said deciding has decided that the difference is within the specified tolerance interval, then said ascertaining ascertains that the re-accessing the web page is indicative of said automatic refresh by the web browser; and

if said deciding has decided that the difference is not within the specified tolerance interval, then said ascertaining ascertains that the re-accessing the web page is not indicative of said automatic refresh by the web browser.

14. The method of claim 13, wherein the specified tolerance interval is defined by a lower bound time and an upper bound time, and wherein the content-update period is greater than the lower bound time and less than the upper bound time.

15. The method of claim 1, wherein said instructing comprises communicating an instruction, as part of a CGI query string, to the server to advance the at least one counter.

16. The method of claim 1, wherein said instructing comprises communicating an instruction, as part of a cookie, to the server to advance the at least one counter.

17. The method of claim 1, wherein said instructing comprises communicating an instruction, as part of a framework, to the server to advance the at least one counter.

18. The method of claim 1, wherein said instructing comprises communicating an instruction, via a request for an uncachable GIF image with a specific query string, to the server to advance the at least one counter.

19. The method of claim 1, wherein the communication network comprises the Internet.

20. The method of claim 1, wherein the communication network comprises an Intranet.
