Redirect Counter for Multi-Threaded Web Loop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infinite redirection loops in web-based applications can lead to performance degradation, security vulnerabilities, and denial of service issues due to multiple HTTP redirects, causing users to encounter access denials or prolonged waiting times.
Innovation Solution
A system and method for managing inter-application communication in a multi-threaded environment, using user-specific application monitoring to limit redirects, with an Internet browser that dynamically tracks redirects and employs a redirect counter to prevent infinite loops, and an application security protection unit to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple HTTP redirects are processed in web-based applications, then application functionality and resource access are improved, but infinite redirection loops occur causing performance degradation and system overload
Solution Approach 1:
The patent implements a redirect counter that is initialized before processing redirects, and a redirect tracking data structure that records redirect information in advance. These preliminary actions enable the system to detect and prevent infinite redirect loops before they can cause system overload, while still allowing legitimate multiple-point redirects to function properly
Solution Approach 2:
The patent employs feedback mechanisms where the redirect counter continuously monitors the number of redirects processed and compares it against a predefined threshold. When the threshold is exceeded, the system terminates further redirects. This closed-loop feedback control prevents infinite loops while permitting necessary redirects within safe limits
2Reliability
If redirect tracking and monitoring mechanisms are implemented, then infinite loops are prevented, but system complexity increases
Solution Approach 1:
The patent divides the redirect monitoring function into separate, modular components: a redirect counter for counting redirects, a redirect tracking data structure for storing redirect information, and a threshold comparison mechanism. This segmentation allows each component to be independently managed and maintained, reducing overall system complexity despite the added functionality
3Reliability
If redirect counter and tracking mechanisms are added, then processing overhead increases, but redirect control and loop prevention are improved
Solution Approach 1:
The redirect counter and tracking mechanism operate autonomously, automatically incrementing the counter, comparing against the threshold, and terminating redirects when necessary without requiring external intervention. This self-service approach minimizes processing overhead by eliminating the need for complex external monitoring systems
Data Source
AI summary
A computer system having a user specified web browsing system for selectively monitoring application request to web based applications to detect and track redirection loops. The web browser of an embodiment of the present invention is configured to track multiple web applications at any given time to determine when to terminate requests to the same application resource when a redirection loops develops to that resource. In one embodiment of the present invention, a user programmable cookie is attached to the web browser to periodically check user specified web applications when a redirection loop is detected. The cookie enables the redirection loop to be terminated when the redirection loop reaches a predetermined maximum number of loops.
