Templated DNS and HTTP Servers for Centralized Domain Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional domain management and HTTP redirection techniques require duplicative and inefficient setup of multiple configurations and HTTP servers for each domain, necessitating repetitive changes for security updates and other modifications.
Innovation Solution
Implementing a templated DNS nameserver and HTTP server that respond to DNS and HTTP/HTTPS requests with predefined responses, eliminating the need for multiple configurations and allowing centralized domain management and redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate DNS zones and HTTP servers are created for each domain, then domain redirection functionality is achieved, but system complexity and configuration duplication increase
Solution Approach 1:
The patent implements a single DNS zone that serves multiple domains through wildcard records, and a single HTTP server that handles multiple domain names. This universal approach allows one configuration to perform the function of multiple separate configurations, eliminating duplication while maintaining the ability to redirect various domains.
Solution Approach 2:
The patent merges multiple DNS zones into a single zone file that contains wildcard records for multiple domains. Similarly, multiple HTTP server configurations are merged into a single server instance that uses the SameSite attribute to manage session cookies across different domain contexts. This consolidation reduces system complexity while preserving domain redirection functionality.
2Manufacturing precision
If manual configuration of each domain is performed, then precise domain control is achieved, but time consumption and operational efficiency decrease
Solution Approach 1:
The patent uses wildcard DNS records as a preliminary configuration that automatically matches multiple domains without requiring individual setup for each domain. The HTTP server is pre-configured with SameSite attribute handling that automatically applies to all domains in the zone, eliminating the need for repetitive manual configuration while maintaining precise control over domain behavior.
Solution Approach 2:
Instead of manually copying and configuring each domain separately, the patent uses wildcard records that automatically replicate the DNS configuration pattern across multiple domains. The single HTTP server configuration effectively copies the domain handling logic to all domains in the zone through the wildcard matching mechanism, dramatically improving configuration efficiency.
3Reliability
If multiple HTTP servers are deployed for different domains, then domain-specific security certificates can be implemented, but resource consumption and maintenance overhead increase
Solution Approach 1:
The patent implements a single HTTP server that universally handles multiple domain names and security certificates. The server is configured to load and manage multiple certificates within a single instance, allowing it to serve multiple domains securely without requiring separate server deployments. This reduces resource consumption while maintaining security functionality.
Solution Approach 2:
The patent merges multiple server instances into a single HTTP server that consolidates the handling of multiple domains and their associated security certificates. By combining certificate management and domain handling in one server process, the system reduces the total number of server instances required while maintaining the ability to implement domain-specific security requirements.

AI summary
In various embodiments, a templated Domain Name System (DNS) nameserver respond to DNS to DNS requests, and a templated HyperText Transfer Protocol (HTTP) server respond to HTTP and Hypertext Transfer Protocol Secure (HTTPS) requests. The templated DNS nameserver responds to a DNS request with a predefined response specifying an Internet Protocol (IP) address associated with the templated HTTP server, based on a type of the DNS request. The templated HTTP server responds to an HTTP or HTTPS request with a redirection response specifying a default redirection Universal Resource Locator (URL), or a different URL if the default has been overridden. Domain management is simplified relative to conventional approaches using the templated DNS nameserver and the templated HTTP server. A new domain can simply be registered at a domain name registrar, and the templated DNS nameserver configured as an authoritative DNS nameserver at the domain name registrar.
