POLLY - RESILIENCY and FAULT HANDLING With HTTP Client | Getting Started With ASP.NET Core Series

An application that depends on external services has to be sensitive to transient faults that can occur. These faults include momentary loss of network connection to the external services, temporary unavailability of a service, timeouts when the service is busy, etc. These faults are usually self-correcting, which means if we retry the same request to the service with a slight delay it's likely to be successful.

These faults include momentary loss of network connection to the external services, temporary unavailability of a service, timeouts when the service is busy, etc. These faults are usually self-correcting, which means if we retry the same request to the service with a slight delay it's likely to be successful.

In this video, let's learn about Polly a .NET resilience and transient fault handling library that allows developers to express various resilience policies in a fluent and thread-safe manner. I will use Fiddler to simulate errors with external API (a weather API in this example) and show you how to gracefully handle these errors using Polly. I will show examples of using Automatic Retry, circuit breaker, and timeout resilience policies.

This video is really good. Thank you for shearing knowledge. I have one question I am not able to install Fiddler Everywhere tool on my company laptop because of privacy policies. Can you suggest me the other way to test retry and unauthorized policies for poly. Thank you

Does circuit breaker reset per user session or for all sessions?
