Page Redirect Loop Detection Using Single-Page Access Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting page redirect loops require complete information of the redirect chain, consuming significant resources and are ineffective in cross-site scenarios due to information acquisition limitations.
Innovation Solution
Detecting a page redirect loop by monitoring a single node page and analyzing the sequence of access times, using methods like Fourier analysis to determine periodicity, reducing resource consumption and enabling detection across multiple sites without full chain information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complete information of the redirect chain is acquired to detect loops, then detection accuracy is improved, but system resource consumption increases significantly
Solution Approach 1:
The patent extracts only the necessary monitoring information (access times of a single node page) from the complete redirect chain, rather than acquiring all chain information. This selective extraction maintains loop detection capability while significantly reducing resource consumption associated with collecting and processing entire redirect chains across multiple sites.
Solution Approach 2:
The patent segments the redirect chain monitoring task into independent node page monitoring units. Each node page is monitored separately for access times, and loops are detected by analyzing periodic patterns in these segmented data points. This segmentation allows parallel processing and reduces the computational burden compared to analyzing complete chains.
2Reliability
If complete redirect chain information is acquired, then loop detection reliability is improved, but applicability in cross-site scenarios deteriorates due to information acquisition limitations
Solution Approach 1:
The patent creates a universal monitoring mechanism that functions across different sites and redirect chain configurations. By monitoring access times at any node page within the redirect chain and analyzing periodic patterns, the system achieves loop detection capability that is adaptable to cross-site scenarios, trusted login flows, and various redirect chain structures without requiring site-specific implementations or complete chain information.
3Device complexity
If a single node page is monitored instead of the entire redirect chain, then implementation complexity is reduced, but detection capability may be compromised
Solution Approach 1:
The patent employs feedback mechanisms by continuously monitoring access times at the node page and analyzing the periodicity patterns of these accesses. The system uses Fourier analysis or other periodicity detection methods on the accumulated access time data to identify loops. This feedback-based approach maintains high detection capability while working with simplified single-page monitoring data, as the periodic patterns in access times provide sufficient information to detect loops without needing complete chain information.

AI summary
A method and an apparatus for detecting a page redirect loop. The method comprises: for a monitored target page, acquiring a sequence of access times at which the target page is accessed (101), the target page being a node page in a page redirect chain; and when it is analyzed that the sequence of access times is periodic, determining that a page redirect loop occurs in the page redirect chain where the target page is included (102). The method is relatively easy to implement and reduces system resource consumption. In addition, even in a cross-site page redirect scenario, since a redirect loop can be determined by monitoring a single page without acquiring information about other sites, the method can be more widely applied.
