Abstract

Methods, systems, and products are disclosed for dynamically updating web content using W3C standards. One such method sends a request to a web server for a web page. A web browser receives and renders a static HTML web page. The web browser periodically sends a query to the web server and, in response, receives a latest date and time stamp indicating the latest update to the web page. The web browser compares the latest date and time stamp to a previously stored date and time stamp representing a previous update. If the latest date and time stamp matches the previously stored date and time stamp, then no update has occurred and no update is required. If, however, the date and time stamps do not match, then the web page has changed since the previous update and the web browser retrieves the latest update to the web page.

Claims

1. A method for dynamically updating content at a web browser using W3C standards, comprising:

sending a request to a web server for a web page;

receiving a web page in response to the request, the web page having a static portion and a dynamic portion;

rendering by the web browser only the static portion of the web page;

periodically sending a query to the web server according to a configurable time parameter, the query requesting a latest date and time associated with the dynamic portion;

receiving a static file having a latest date and time stamp included therein, the latest date and time stamp indicating a most recent version of the dynamic portion of the web page;

comparing by the web browser the latest date and time stamp to a previously stored date and time stamp, the previously stored date and time stamp representing a previous version of the dynamic portion of the web page;

when the web browser retrieves a null or empty response for the previously stored date and time stamp, then querying a data source for the most recent version of the dynamic portion of the web page;

retrieving the most recent version of the dynamic portion of the web page; and

rendering by the web browser the most recent version of the dynamic portion of the web page.

2. A method according to claim 1, wherein if the latest date and time stamp matches the previously stored date and time stamp, then further comprising rendering the dynamic portion received from the web server, as no update to the dynamic portion has occurred and the web page is not updated.

3. A method according to claim 1, wherein if the latest date and time stamp does not match the previously stored date and time stamp, then the dynamic portion of the web page has changed since the previous update and the web browser retrieves the most recent version of the dynamic portion from the data source.

4. A method according to claim 1, wherein periodically sending the query comprises periodically sending the query according to the configurable time parameter of one second.

5. A method according to claim 1, further comprising associating a tag in the static portion of the web page with updated content.

6. A method according to claim 1, further comprising instructing the web browser to run a routine “

getupdateXML”

after the web page is loaded.

7. A method according to claim 3, further comprising refreshing the web browser with the most recent version of the dynamic portion from the data source.

8. A system, comprising:

a processor executing code stored in memory, the code causing the processor to;

send a request to a web server for a web page;

receive a web page in response to the request, the web page having a static portion and a dynamic portion;

render by the web browser only the static portion of the web page;

periodically send a query to the web server according to a configurable time parameter, the query requesting a latest date and time associated with the dynamic portion;

receive a static file having a latest date and time stamp included therein, the latest date and time stamp indicating a most recent version of the dynamic portion of the web page;

compare by the web browser the latest date and time stamp to a previously stored date and time stamp, the previously stored date and time stamp representing a previous version of the dynamic portion of the web page;

when the web browser retrieves a null or empty response for the previously stored date and time stamp, then query a data source for the most recent version of the dynamic portion of the web page;

retrieve the most recent version of the dynamic portion of the web page; and

render by the web browser the most recent version of the dynamic portion of the web page.

9. A system according to claim 8, wherein if the latest date and time stamp matches the previously stored date and time stamp, then the code further causes the processor to render the dynamic portion received from the web server, as no update to the dynamic portion has occurred and the web page is not updated.

10. A system according to claim 8, wherein if the latest date and time stamp does not match the previously stored date and time stamp, then the code further causes the processor to retrieve the most recent version of the dynamic portion from the data source, as the dynamic portion of the web page has changed since the previous update.

11. A system according to claim 8, wherein the code further causes the processor to periodically send the query according to the configurable time parameter of one second.

12. A system according to claim 8, wherein the code further causes the processor to associate a tag in the static portion of the web page with updated content.

13. A system according to claim 8, wherein the code further causes the processor to instruct the web browser to run a routine “

getupdateXML”

after the web page is loaded.

14. A system according to claim 10, wherein the code further causes the processor to refresh the web browser with the most recent version of the dynamic portion from the data source.

15. A computer program product comprising a computer readable medium storing processor executable code for performing a method, the method comprising:

sending a request to a web server for a web page;

receiving a web page in response to the request, the web page having a static portion and a dynamic portion;

rendering by the web browser only the static portion of the web page;

periodically sending a query to the web server according to a configurable time parameter, the query requesting a latest date and time associated with the dynamic portion;

receiving a static file having a latest date and time stamp included therein, the latest date and time stamp indicating a most recent version of the dynamic portion of the web page;

comparing by the web browser the latest date and time stamp to a previously stored date and time stamp, the previously stored date and time stamp representing a previous version of the dynamic portion of the web page;

when the web browser retrieves a null or empty response for the previously stored date and time stamp, then querying a data source for the most recent version of the dynamic portion of the web page;

retrieving the most recent version of the dynamic portion of the web page; and

rendering by the web browser the most recent version of the dynamic portion of the web page.

16. A computer program product according to claim 15, further comprising computer code for wherein if the latest date and time stamp matches the previously stored date and time stamp, further comprising rendering the dynamic portion received from the web server, as no update to the dynamic portion has occurred and the web page is not updated.

17. A computer program product according to claim 15, further comprising computer code for wherein if the latest date and time stamp does not match the previously stored date and time stamp, then the dynamic portion of the web page has changed since the previous update and the web browser retrieves the most recent version of the dynamic portion from the data source.

18. A computer program product according to claim 15, further comprising computer code for periodically sending the query according to the configurable time parameter of one second.

19. A computer program product according to claim 15, further comprising computer code for associating a tag in the static portion of the web page with updated content.

20. A computer program product according to claim 15, further comprising computer code that instructs the web browser to run a routine “

getupdateXML”

after the web page is loaded.
