Overview

This class resolves JSON schema references (e.g., “$ref”: “example.com/schema.json”) by fetching remote schemas over HTTP/HTTPS and caching them. It is used by JSONSchemer to resolve external schema definitions. We need it to validate JSON data against schemas that might be hosted remotely.
