Websites are becoming larger in size, more complex in what they display and are updated with greater frequency than ever before. This means users can receive up to date, complex information. But what this also means is that whenever new information is presented, whether it be a new image, new text within a paragraph, or subtle changes to layout, the user has to download all of the information again. Web browsers will cache information and store blocks of information. However, with continually updating web pages becoming the norm, the way in which web browsers cache needs improvement. This solution provides a way in which smaller downloads are required, a greater understanding of updates is shown and makes sure that the user is always presented with the most recent information. Even if that information is within a non-obvious location.

Automated server side web version control to limit sent/downloaded information in web browsers

This disclosure presents a caching protocol for use with web browsers that compares a timestamp or a version number of a cached web page on a computer or mobile device with the timestamps or versions of that particular web page on that

website's server such that only the differences between the two web pages are downloaded, thus improving download efficiency.

    When a user downloads a web page for the first time, the web page is cached and a timestamp is taken of the time at which they downloaded the aforementioned web page, or similarly a version number could be supplied. When a user wishes to access this page again, a request is sent along with the timestamp or version number of the most recently cached version of the web page. The server can then review the change set history of the web page and only send a change set of the content that was created or modified after the timestamp or version number. This comprises of the modified content and markers where this content will be inserted into the web page or previous content will be deleted from the web page.

This enables mobile users to update their content to the latest version of the

web page without having to redownload the full contents of the web page, as in other known systems. Taking the example of a live text feed from a web page, which

can involve large amounts of content but the user only wants the new, up to date content (and what is defined as up-to-date varies from user to user). The proposed system accepts the change set and information about where to place the change set but does not redownload images and text th...
