Declarative Web Site Mapping for Scalable Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing scalable dynamic web applications is challenging due to the inefficiencies and complexities inherent in existing technologies, such as ASP.NET, which require extensive resources and manual management of web site content.
Innovation Solution
Implementing web site development using lazily evaluated declarative mapping data structures, where only the necessary parts of the mapping data structure are calculated for each HTTP request, promoting efficiency and flexibility through recursive mappings and lazy expression evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional web application frameworks (e.g., ASP.NET) are used to build dynamic web sites, then functionality and scalability are achieved, but resource consumption and system complexity increase significantly
Solution Approach 1:
The patent segments the web site content into discrete, independently addressable units organized in a hierarchical namespace. Each content unit can be independently retrieved, cached, and served, eliminating the need to load and process entire web applications or pages. This segmentation allows the system to serve only the specific content requested, dramatically reducing resource consumption while maintaining scalability.
Solution Approach 2:
The system pre-organizes web site content into a hierarchical namespace structure with defined relationships between parent and child content units. This preliminary organization enables efficient navigation and retrieval operations, where the system can quickly locate and serve specific content without needing to process or interpret complex application logic at request time, reducing computational resources while supporting scalable growth.
2Ease of operation
If manual management of web site content is implemented, then control and flexibility are maintained, but development time and operational complexity increase
Solution Approach 1:
The patent implements a universal hierarchical namespace structure that can accommodate any type of web content (HTML, images, videos, documents, etc.) and any organizational scheme. This universal framework provides both automatic routing capabilities and flexible manual management options, allowing operators to control content placement and relationships while the system handles the complexity of navigation and retrieval automatically, reducing development time without sacrificing flexibility.
3Speed
If complete web site content is loaded into memory for serving, then fast access is achieved, but memory requirements and storage costs increase
Solution Approach 1:
The patent extracts only the specific content unit requested by the user from the larger web site hierarchy and serves it independently. Instead of loading entire web pages or application contexts into memory, the system retrieves only the necessary content unit and its immediate dependencies, dramatically reducing memory requirements while maintaining fast access speeds for the requested content.
Solution Approach 2:
The system implements a nested hierarchical structure where content units are organized in parent-child relationships within the namespace. This nesting allows the system to load and cache only the specific content unit and its immediate parent/child relationships needed for the current request, rather than loading the entire web site structure. The hierarchical nesting enables efficient memory usage by loading content in manageable, nested portions.

AI summary
Web sites are modeled using mappings from paths to expressions. A mapping data structure of expressions represents a web site's hierarchical structure, and an enumerator, an array of characters, or an array of bytes represents the web site's content. Expressions are written in a declarative programming language, and are lazily evaluated to provide results used in HTTP responses. A mapping may be recursive. An expression may contain a function call which returns contents of a file named in the HTTP request path, or the expression may evaluate to a text string, for example. Expressions may call functions which produce side-effects. An expression may recursively map a directory name to a mapping of a file name. Scalability is promoted by concurrently evaluating expression(s) on different machines in a stateless middle tier, and by streaming results. An arbitrarily large web site may be implemented in this manner.
