HTML Sectors: An Enhancement beyond Frame and IFrame

  Description: Web browser pages can contain a lot of information. When a page refreshes, and the entire page is regenerated, this could cause a lot of processing to occur on a web application server and on backend databases or other applications. Also, this could cause other plugins or other <IFRAME>'s to restart themselves; thus, unexpectedly changing the content being displayed. This idea describes a technique when a web browser could update only part of the web page, rather than updating the entire web page, and potentially preventing a processing burden on the web application server and other backend processes, and restarting any plugins.

Problem Solved: There are two problems solved.

One is a performance problem. This is the performance impact on the web application server and potentially on any backend databases or processes, to rebuild a web page unnecessarily.

The second problem solved relates to unnecessary restarting of other applications. This includes items like rebuilding an internal frame <IFRAME>, and thus causing an unexpected change in the displayed content. This also includes the restarting of applets, SVG Viewers, and other plugins. The reverse is also true, that a portion of the web browser page can be updated without affecting the displayable content of the rest of the browser page. For example, Javascript could cause a portion of the web browser page to auto-refresh a graph, that would not affect the rest of the web page.

Advantages of using this idea: One advantage is quicker refresh of the web browser page, because parts of the browser page that should not be refreshed do not incur the processing expenditure on the web application server and backend databases or other processes.

Another advantage is the prevention of unexpected change in the displayed browser page. This unexpected change occurs with browser <IFRAME>'s where the content could be reset, when the entire web page is refreshed. This unexpected change also occurs with applets, because the applet will be restarted. This also occurs with SVG, as the SVG viewer would restart a potentially animated graph. This could occurs with other plugins as well. And the reverse advantage is that a portions of the web browser page can be auto-refreshed, without affecting the displayable content of the rest of the browser page.

How does the idea solve the problem or achieve an advantage?

In the HTML standard, a new HTML tag would be invented. For the sake of this write-up let's call it <SECTOR>, with a corresponding ending tag of </SECTOR>. This new HTML tag could be anything. The <SECTOR> tag would be interpreted by the browsers, to delineate a section of the HTML markup that could be independently updated by the web application server.
