http-client-resilience

Rationale

HTTP calls to external services are inherently unreliable. Network issues, service outages, and transient failures are common in distributed systems. Without proper resilience patterns, your application will experience cascading failures. These patterns using IHttpClientFactory and Polly provide production-grade reliability for HTTP communication.

Patterns

Pattern 1: Named HttpClient with Resilience

Configure named clients with comprehensive resilience policies including retry, circuit breaker, and timeout.
