DotNet-Retry-Example

This repository provides an example of how to implement a custom HttpClient handler for retrying HTTP requests in the DocuWare platform server client. The retry policies in RetryHandler and RetryHandlerWithPolly demonstrate handling HTTP 502 (Bad Gateway), HTTP 503 (Service Unavailable), and HTTP 504 (Gateway Timeout) errors by retrying the requests a specified number of times with a delay between each retry. The retry policy in RetryHandlerWithPollyAndExponentialBackoff demonstrates handling HTTP 408 (Request Timeout) errors and all errors with status codes 500 (Internal Server Error) and above using an exponential backoff strategy.

Project Structure

The solution consists of multiple projects targeting different .NET frameworks:

• retry-example-error-502-and-504-dot-net8: A .NET 8.0 console application demonstrating the retry policy.
• retry-example-error-502-and-504-dot-net-framework-472: A .NET Framework 4.7.2 console application demonstrating the retry policy.
• retry-example-error-502-and-504-retry-policy-dot-net-standard-2: A .NET Standard 2.0 library implementing the retry policy.
• retry-example-error-502-and-504-tests-dot-net8: A .NET 8.0 test project containing unit tests for the retry policy.
• retry-example-error-502-and-504-benchmarks-dot-net8: A .NET 8.0 project containing benchmarks for the retry policy.
