Technical Summary: WebSpark.HttpClientUtility WebSpark.HttpClientUtility is an enterprise-grade HTTP client wrapper library for .NET 8-10 LTS that abstracts away boilerplate HttpClient configuration by providing integrated resilience patterns (Polly), intelligent response caching, structured logging with correlation IDs, and OpenTelemetry observability—all configurable through a single AddHttpClientUtility() dependency injection call. The library is delivered as two focused NuGet packages: the core utility package (163 KB) for standard HTTP operations and a companion Crawler package (75 KB) for web scraping with robots.txt parsing and sitemap generation. Built with production-grade standards including comprehensive automated test coverage across .NET versions, Source Link debugging support, Native AOT and trimming compatibility, and strict semantic versioning guarantees, it targets microservices architects and backend developers who want to eliminate 50+ lines of manual HttpClient setup code while maintaining battle-tested reliability patterns. The project demonstrates modern .NET practices through zero-warning builds, package validation for breaking change detection, and CI/CD integration via GitHub Actions, though the repository itself shows no recent activity (stale for 90+ days) despite being MIT-licensed and backed by comprehensive documentation at a live reference site.
