Proxy Server Head Start Chunk for Web Page Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current web page loading times are inefficient due to the sequential loading of resources, which affects user experience and revenue, as web browsers wait for the entire page to be delivered before fetching resources specified in the HTML 'head' section.
Innovation Solution
Implementing an optimistic transmission method where a proxy server transmits a predicted static portion of the web page, known as the 'head start chunk,' to the client device before retrieving the full page, allowing parallel resource loading and reducing initial load time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the web browser waits for the entire page to be delivered before fetching resources, then the page structure is complete, but the loading time increases
Solution Approach 1:
The patent segments the web page into the head section (containing resources) and the body section (containing content). By separating these segments, the browser can fetch and process the head section independently before the body is fully received, enabling parallel resource loading without compromising page completeness.
Solution Approach 2:
The patent implements preliminary action by fetching the head section resources (scripts, styles, images) before the entire page is delivered. The browser proactively retrieves these resources in advance, processes them, and makes them available before the body content is fully received, thereby reducing overall loading time while maintaining page integrity.
2Loss of time
If resources are loaded sequentially, then the process is simple, but the loading time increases
Solution Approach 1:
The patent employs preliminary action by having the browser fetch head section resources in advance before the body is completely received. This allows resources to be prepared beforehand and made available for immediate use, enabling parallel processing and reducing total loading time.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining parallel resource loading operations that continue simultaneously with page reception. The browser continuously fetches and processes resources in the background without interrupting the main page download, keeping the loading process efficient and uninterrupted.
3Speed
If the head section is fetched in parallel, then the loading speed improves, but the complexity of resource management increases
Solution Approach 1:
The patent segments resources into the head section (scripts, styles, images) and body section (content). This segmentation allows the browser to manage and fetch head resources in parallel independently from the body, improving loading speed while maintaining manageable complexity through clear separation of resource types.

AI summary
A proxy server receives a request for a web page from a client device. In response to determining that a portion of the web page is available in cache, the proxy server retrieves that portion and transmits it to the client device. The portion of the web page is not the entire web page and is a prediction of the portion of the page that will remain static if the page is reloaded or requested by a different client device. The proxy server transmits a request to an origin server for the full web page. In response to receiving the full web page from the origin server, the proxy server modifies the full web page to remove the portion that was already transmitted to the client device, and transmits the modified web page to the client device.
