Simple Flowchart Diagram Illustration

This clear and concise flowchart illustrates a request processing workflow, focusing on how requests are managed, assigned unique identifiers, and routed based on caching permissions. It details the steps for handling requests, including checks for existing similar requests and allocation to either a cache queue for new cacheable requests, a waiting queue for duplicate cacheable requests, or directly to a network queue for non-cacheable items. The diagram uses standard flowchart symbols to visually represent decisions and processes, making it easy to understand the logic of the request handling system.
