Proxy System Pre-fetching Linked Content for Policy Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Web proxy systems are limited in their ability to perform detailed and customized content analysis due to the need for quick page rendering, which restricts the depth of analysis and can result in users discovering blocked access only after clicking on a link, leading to frustration and inefficiency.
Innovation Solution
A proxy system that pre-fetches linked content and analyzes it according to a content policy, allowing access to the pre-fetched content in accordance with the policy and rendering allowed content for the user, thereby enhancing browsing experience and enabling more detailed analysis without increasing page rendering latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If content analysis is performed when the page is first fetched, then the depth of analysis can be increased, but the page rendering latency increases
Solution Approach 1:
The patent applies preliminary action by pre-fetching and analyzing content in advance before the user actually requests it. The system identifies linked content in the current page, pre-fetches it, and performs content analysis on the pre-fetched content before the user clicks on links. This allows detailed analysis to be completed beforehand, so when the user requests the content, it can be rendered immediately without analysis delays.
2Measurement precision
If detailed and customized analysis of Web pages is performed, then the content filtering accuracy is improved, but the processing time increases
Solution Approach 1:
The system performs detailed and customized content analysis in advance on pre-fetched content. By analyzing the content before it is requested, the system can apply complex filtering rules, categorization, and customization without impacting the user's experience. The analysis results are stored and ready for quick retrieval when needed.
Solution Approach 2:
The patent segments the content processing into distinct phases: pre-fetching phase, analysis phase, and rendering phase. The content analysis is performed on segmented portions of content (pre-fetched linked content) rather than all content at once. This segmentation allows detailed analysis to be performed systematically without overwhelming the system or delaying user requests.
3Ease of operation
If a traditional Web proxy is used, then the client configuration is simple, but the user can bypass the proxy and the administrative burden increases
Solution Approach 1:
The patent employs an intercepting proxy that acts as an intermediary between the client and the internet. The proxy server intercepts HTTP requests from client browsers and redirects them through the proxy without requiring any client-side configuration. This intermediary approach maintains ease of operation for users while giving administrators full control over content filtering and policy enforcement.
4Loss of energy
If content is fetched only when explicitly requested, then the bandwidth usage is reduced, but the user experience deteriorates due to loading delays
Solution Approach 1:
The system applies preliminary action by pre-fetching content that is likely to be requested based on links found in the current page. Instead of fetching content only when explicitly requested, the system anticipates user needs and retrieves related content in advance. This reduces perceived waiting time for users while maintaining efficient bandwidth usage by only pre-fetching relevant linked content.

AI summary
Certain embodiments of the present invention provide methods and systems for providing access to network content. Certain embodiments provide a proxy system for providing access to network content. The system includes a content retriever for retrieving a first content on a network. The content retriever is configured to pre-fetch additional content linked or connected to the first content. The system also includes a content analyzer for analyzing the first content and the pre-fetched additional content according to a content policy and allowing access to the first content and the pre-fetched additional content in accordance with the content policy. The system further includes a content renderer for rendering allowed content for provision to a user upon user request. The renderer can also modify links to content based on a status of the linked content.
