In-Server HTTP Redirection for Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HTTP redirect technologies require clients to re-submit URL requests after receiving redirection commands, leading to increased network bandwidth usage, higher communication costs, and reduced response rates, especially in mobile networks, due to the need for multiple requests and lack of internal redirection capabilities within the server.
Innovation Solution
A method and system where the HTTP server internally identifies and processes redirections, sending the true URL content to the client without requiring the client to support redirection commands, by analyzing the HTTP response and submitting requests to either the target or redirected URLs as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standardized HTTP redirect function is used, then clients can be redirected to relevant webpages, but network bandwidth is wasted and communication costs increase due to multiple requests
Solution Approach 1:
The server performs the redirect action in advance by including the final URL directly in the initial HTTP response body, eliminating the need for clients to issue subsequent requests to resolve redirects. This preliminary provision of the final destination resolves the contradiction by maintaining redirect adaptability while preventing the bandwidth waste that would result from multiple request-response cycles.
2Adaptability or versatility
If standardized HTTP redirect function is used, then URL redirection can be achieved, but response rate is reduced due to client needing to re-submit requests
Solution Approach 1:
The server provides the final URL in the initial response, performing the redirect resolution before the client needs to act. This eliminates the sequential delay where the client must wait for the redirect response, then submit a new request, then wait for the final response. The redirect function is maintained while response rate is improved by removing the intermediate request-submission step.
3Adaptability or versatility
If HTTP server returns redirection command, then clients can be directed to new URLs, but client-side redirection capability is required which complicates the client
Solution Approach 1:
The redirect functionality is extracted from the client and moved to the server. Instead of the client receiving a redirect command and needing to process it independently, the server directly includes the final URL in the response body, making the redirect transparent to the client. This maintains the adaptability of URL redirection while eliminating the need for complex client-side redirect handling capabilities.
4Measurement precision
If multiple requests are submitted for redirection, then accurate URL content can be obtained, but user experience deteriorates due to increased communication time
Solution Approach 1:
The server performs the redirect resolution in advance and includes the accurate final URL directly in the initial response. This eliminates the time loss associated with multiple request-response cycles while maintaining the accuracy of the URL content, as the server has already resolved the redirect chain before sending the response to the client.

AI summary
A method and system for HTTP request service identify a true URL content regardless of whether the target URL is redirected, and send the true URL content to a client. The requesting and sending of the redirected URL content is done internally in the HTTP server system and do not require the client to have the ability to receive and execute a URL redirection command. The server system receives a URL request from the client and generates within the server a response to the URL request. If the response does not contain any redirection information, the true URL content includes the target URL content; and if the response contains redirection information indicating a redirected URL, the true URL content includes a redirected URL content associated with the redirected URL. The client receives the true URL content in either case by submitting a request for the target URL once.
