Single-Click URL Slug Locking to Prevent Double Actions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In single-click environments, multiple requests associated with contradictory workflows can lead to wastage of power and processing resources and errors due to concurrent execution of actions, which existing systems fail to prevent effectively.
Innovation Solution
A URL slug encoding a concurrency control indicator is used to determine if an action is part of a concurrency control group, with a remote database implementing distributed locking to ensure actions are executed only when the group is unlocked, thereby preventing double actions and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If single-click URLs are used to expedite actions, then processing speed is improved, but the risk of concurrent execution of contradictory workflows increases
Solution Approach 1:
The system performs preliminary actions by encoding concurrency control indicators in URL slugs before the user clicks. When a URL is requested, the system proactively checks the concurrency status and locks the resource if needed, preventing concurrent execution before it can occur. This advance preparation maintains both speed and reliability.
Solution Approach 2:
The patent introduces a concurrency control mechanism as an intermediary between the single-click URL and the action execution. The slug-encoded indicator acts as a mediator that coordinates access to shared resources, allowing fast single-click processing while preventing contradictory workflows from executing simultaneously through centralized lock management.
2Reliability
If concurrency control checks are implemented, then workflow integrity is improved, but network overhead increases
Solution Approach 1:
The patent extracts the concurrency control indicator from complex authentication credentials and embeds it directly in the URL slug. This separation allows the system to perform lightweight local checks using the slug indicator without requiring full credential verification or extensive network communication, reducing overhead while maintaining reliability.
Solution Approach 2:
The URL slug itself carries the concurrency control information, allowing the system to self-verify concurrency status without external authentication. The embedded indicator enables the web instance to autonomously determine whether to proceed with action execution, minimizing network round-trips and reducing energy consumption.
3Manufacturing precision
If distributed locking is used to prevent double actions, then action accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements local quality by encoding concurrency control information specifically in the URL slug portion rather than requiring system-wide changes. Each URL carries its own concurrency indicator, allowing distributed locking to be implemented locally at the URL processing level without complicating the overall system architecture.
Solution Approach 2:
The system changes parameters by using a bit or indicator within the existing URL slug structure to convey concurrency control information. This parameter encoding approach allows distributed locking functionality to be added without introducing new complex data structures or communication protocols, maintaining system simplicity while achieving high action accuracy.
Data Source
AI summary
In some implementations, a web instance may receive an indication of an event associated with a uniform resource locator (URL) that includes a slug. The web instance may determine, using an indicator encoded in the slug, that the URL is associated with an action that is included in a concurrency control group. The web instance may communicate with a remote database to determine whether the concurrency control group is locked. The web instance may selectively trigger execution of the action based on whether the concurrency control group is locked.
