HttpClient Timeout When Using Polly for Retry Policy in .NET 6
I'm learning this framework and I'm prototyping a solution and I've looked through the documentation and I'm still confused about I'm trying to implement a retry policy using Polly in my .NET 6 application with `HttpClient`, but I'm running into issues where the request times out after the first retry attempt... My intention is to have the request automatically retry on specific exceptions without exceeding a total timeout limit. However, it seems like the total duration of all retries is still being capped by the default `HttpClient` timeout. Here's the code snippet I'm using to configure the `HttpClient` and Polly: ```csharp var retryPolicy = Policy .Handle<HttpRequestException>() .Or<TaskCanceledException>() .WaitAndRetryAsync(3, retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))); var httpClient = new HttpClient { Timeout = TimeSpan.FromSeconds(10) // Default timeout }; var response = await retryPolicy.ExecuteAsync(async () => await httpClient.GetAsync("https://api.example.com/data")); ``` When I run this code, I often get a `TaskCanceledException` indicating that the request timed out, even if a retry is attempted. I've confirmed that the API endpoint is reachable and has a response time well under 10 seconds. I've also tried removing the `httpClient.Timeout` setting and just letting it use the default timeout, but that didn't solve the scenario either. I suspect the scenario might be related to how `HttpClient` is managing the timeout during the retries, but I need to find concrete documentation on this behavior. How can I properly configure the `HttpClient` with Polly so that it handles retries without hitting the timeout behavior? Is there a recommended way to set up the retry policy without making the initial request unexpected result immediately? Any help would be appreciated. For context: I'm using C# on Windows. The stack includes C# and several other technologies. This is my first time working with C# 3.9. I'd love to hear your thoughts on this.
