Abstract

The updating of an original version of a Web page without having to download the entire Web page. After accessing an original version of a Web page, a browser client detects that the accessed original version of the Web page is to be updated. The browser client then requests an updated version of the Web page from a page server computing system. Thereupon, the page server determines that only a portion of the updated version of the Web page is to be downloaded to the browser client, identifies that portion, and sends a response to the browser client that includes at least the portions of the Web page that have changed, but less than all of the Web page. The browser client then partially renders the updated version of the Web page using the portions of the Web page provided in the response.

Claims

1. In a network that includes a browser client computing system and at least one page server computing system that offers at least one Web page, a method for the browser client to update an original version of the Web page without having to download the entire Web page, the method comprising:

an act of a browser on the browser client computing system requesting an original version of a Web page from the page server computing system;

an act of the browser receiving the original version of the Web page in its entirety from the page server computing system in response to the act of requesting the original version of the Web page, the original version of the Web page including a partial update script;

an act of the browser displaying the original version of the Web page;

an act of the partial update script registering with the browser to be notified when user input to the browser invokes functionality of the Web page that instructs the browser to request an update to the original version of the Web page that would cause the entire Web page to be reloaded;

an act of the browser receiving input that invokes the functionality of the Web page that instructs the browser to request an update to the original version of the Web page that would cause the entire Web page to be reloaded;

an act of the browser notifying the partial update script of the request to update the original version of the Web page;

an act of the partial update script receiving the notification;

an act of the partial update script preventing the browser from requesting the update;

after preventing the browser from requesting the update, an act of the partial update script requesting a partial updated version of the Web page from the page server computing system;

an act of receiving the partial updated version of the Web page from the page server computing system in response to the act of requesting the partial updated version of the Web page, wherein the partial updated version of the Web page includes at least any components of the Web page that have changed between the original and partial updated versions of the Web page, but includes less than all of the components of the Web page; and

an act of partially rendering the partial updated version of the Web page without re-rendering the entire Web page.

2. A method in accordance with claim 1, wherein the Web page includes markup language.

3. A method in accordance with claim 1, wherein the Web page also includes content that is included in-line with the markup language, but does not include content that is only referred to in the markup language.

4. A method in accordance with claim 1, wherein the components of the Web page that have changed are represented in the response using markup language, wherein the act of partially rendering comprise an act of rendering using the markup language.

5. A method in accordance with claim 1, wherein the components of the Web page that have changed are represented in the response using script, wherein the act of partially rendering comprise an act of executing the script.

6. A method in accordance with claim 1, wherein the act of the partial update script requesting a partial updated version of the Web page from the page server computing system comprises:

generating an HTTP POST request and including a custom partial update header in the request that indicates to the page server computing system that the request is for a partial update of the Web page rather than for an update to the entire Web page.

7. A method in accordance with claim 1, further comprising:

an act of the browser receiving input into one or more fields of the Web page; and

in response to the input, an act of the browser sending events to the page server computing system indicating that input has been received into the one or more fields of the Web page, wherein upon the partial update script requesting the partial updated version of the Web page, the page server computing system uses the received events to determine which portions of the Web page are to be updated.

8. A computer program product for use in a network that includes a browser client computing system and at least one page server computing system that offers at least one Web page, the computer program product comprising one or more computer storage media having thereon computer-executable instructions that, when executed by one or more processors of the browser client computing system, cause the browser client computing system to perform the following:

an act of a browser on the browser client computing system requesting an original version of a Web page from the page server computing system;

an act of the browser receiving the original version of the Web page in its entirety from the page server computing system in response to the act of requesting the original version of the Web page, the original version of the Web page including a partial update script;

an act of the browser displaying the original version of the Web page;

an act of the partial update script registering with the browser to be notified when user input to the browser invokes functionality of the Web page that instructs the browser to request an update to the original version of the Web page that would cause the entire Web page to be reloaded;

an act of the browser receiving input that invokes the functionality of the Web page that instructs the browser to request an update to the original version of the Web page that would cause the entire Web page to be reloaded;

an act of the browser notifying the partial update script of the request to update the original version of the Web;

page;

an act of the partial update script receiving the notification;

an act of the partial update script preventing the browser from requesting the update;

after preventing the browser from requesting the update, an act of the partial update script requesting a partial updated version of the Web page from the page server computing system;

an act of receiving the partial updated version of the Web page from the page server computing system in response to the act of requesting the partial updated version of the Web page, wherein the partial updated version of the Web page includes at least any components of the Web page that have changed between the original and partial updated versions of the Web page, but includes less than all of the components of the Web page; and

an act of partially rendering the partial updated version of the Web page without re-rendering the entire Web page.

9. A computer program product in accordance with claim 8, wherein the Web page includes markup language.

10. A computer program product in accordance with claim 9, wherein the partial updated version of the Web page includes script.
