HTTP Client Cache Content Display Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing HTTP-based content acquisition methods cause delays in displaying content on clients due to server validity verification processes, which reduce display efficiency.
Innovation Solution
The proposed method involves a client acquiring content from a cache, displaying it, and requesting server verification only when the content's validity period expires, while simultaneously acquiring and displaying new content if verification fails, and performing automatic refreshes after preset time intervals to ensure timely updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the client requests the server to verify validity of the content before displaying, then the content validity is ensured, but the display efficiency is reduced due to verification delay
Solution Approach 1:
The client performs validity verification in advance by checking the validity period of cached content before displaying. If the content is still within its validity period, the server's verification is skipped. This preliminary check avoids unnecessary verification delays while ensuring content validity, thus resolving the contradiction between reliability and display efficiency
Solution Approach 2:
The client autonomously determines content validity by comparing the current time with the validity period stored in the cache, without requiring server verification for every content display. This self-service mechanism eliminates dependency on server verification, improving display efficiency while maintaining content reliability through local validity checking
2Reliability
If the client always requests new content from the server, then the content is always updated, but the network bandwidth is wasted and server load increases
Solution Approach 1:
The client checks the validity period of cached content before requesting new content from the server. If the cached content is still valid (within its validity period), the client uses the cached version without contacting the server. This preliminary validity check prevents unnecessary network requests, saving bandwidth and reducing server load while ensuring content freshness through validity-based updates
Solution Approach 2:
The client periodically checks content validity based on the stored validity period and only requests updates when the validity period expires. This periodic validation mechanism ensures content freshness without continuous network communication, optimizing bandwidth usage and server load while maintaining up-to-date content

AI summary
Embodiments of the present invention provide an HTTP-based content acquisition method and client. A method includes: acquiring, by a client according to an acquired content identifier, a first content corresponding to the content identifier and a validity period of the first content from a cache; displaying, by the client, the first content; requesting, by the client according to the validity period of the first content, a server to verify validity of the first content; requesting, by the client, to acquire a second content corresponding to the content identifier from the server if the validity verification performed by the server for the first content fails; and displaying, by the client, the second content. In this way, the time of displaying the content on the client can be shortened, thereby improving the display efficiency of the client.
