Proxy Server Synchronizer for Web Scraping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Web scraping technologies face challenges in efficiently accessing data from websites due to detection by content providers, which leads to blocking and rate limitations, necessitating advanced proxying methods to mimic organic behavior and avoid detection.
Innovation Solution
Implementing advanced proxying techniques, such as using HTTP/2 and HTTP/3 protocols with QUIC, and migrating scraping functionality to last-mile proxies to create multiple connections and encrypt traffic, allowing for undetectable data collection while portraying organic behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If web scraping tools access data from websites, then data collection efficiency is improved, but detection by content providers leads to blocking and rate limitations
Solution Approach 1:
The patent introduces a proxy server as an intermediary between the web scraping tool and the target website. The proxy server receives scraping requests, forwards them to the website, and relays responses back. This intermediary layer masks the true origin of requests, making it difficult for content providers to detect and block scraping activities, thus maintaining both high data collection efficiency and reliable access
Solution Approach 2:
The patent segments the scraping system into multiple distributed proxy servers rather than using a single centralized scraping tool. Each proxy server operates independently to make requests, distributing the scraping load across multiple nodes. This segmentation prevents rate limiting on individual proxies and reduces the likelihood of complete blocking, maintaining productivity while improving reliability
2Reliability
If multiple proxy servers are used to avoid detection, then access reliability is improved, but synchronization of scraping state becomes complex
Solution Approach 1:
The patent merges the state management functionality into a centralized state synchronization service that all proxy servers connect to. Each proxy server maintains its local scraping state and periodically synchronizes with the central service, which consolidates state from all proxies and redistributes relevant information. This combining approach maintains access reliability through distributed proxies while reducing synchronization complexity through centralized coordination
Solution Approach 2:
The patent implements a feedback mechanism where proxy servers report their scraping state and performance metrics to the state synchronization service, which then provides feedback about overall system state, detected patterns, and coordination instructions. This feedback loop enables automatic adjustment of scraping behavior across the proxy network, maintaining reliability while managing synchronization complexity through intelligent feedback-driven coordination
3Object-affected harmful factors
If scraping functionality is migrated to last-mile proxies, then detection resistance is improved, but infrastructure complexity increases
Solution Approach 1:
The patent enables proxy servers to autonomously perform scraping operations without requiring constant control from the original scraping tool. Each proxy server independently manages its own request generation, state maintenance, and response processing. This self-service capability increases detection resistance by making scraping operations appear to originate from diverse locations while the infrastructure manages complexity through standardized automated protocols

AI summary
Systems and methods of web crawling/scraping process implementation are extended and target the web crawling process by submitting a request by a last-mile proxy to a web target. The systems and methods allow a request for a web crawler to be directed toward the target content platform through a proxy, or a plurality of proxies, for the purpose of optimizing the processing of the request. In at least one aspect, the systems and methods disclosed mitigate the potential for a negative evaluation of the requests by the content platform targeted through introducing the transfer of the execution of the steps within a scraping flow within the last-mile proxy system, thus aligning both network and application layer responses to the tests described.
