Question 1

How do I implement offline caching with Fusillade in a .NET app?

Accepted Answer

You need to implement the IRequestCache interface or use a library like Akavache to handle response storage. Fusillade provides hooks via cacheResultFunc or by setting NetCache.RequestCache, but caching logic is external, requiring additional code for save and fetch operations.

Question 2

Does Fusillade support POST request deduplication?

Accepted Answer

No, Fusillade only deduplicates GET, HEAD, and OPTIONS requests for safety, as mentioned in the README. POST and other non-idempotent methods are excluded to prevent unintended side effects from duplicate submissions.

Question 3

Fusillade vs HttpClientFactory: which is better for .NET HTTP management?

Accepted Answer

Fusillade focuses on client-side optimizations like deduplication and prioritization for mobile/desktop apps, while HttpClientFactory is more about server-side resilience and dependency injection. Choose Fusillade for advanced request scheduling in UI apps; HttpClientFactory for microservices and server-side scenarios.

Question 4

How to cancel speculative requests in Fusillade?

Accepted Answer

Use NetCache.Speculative.ResetLimit(-1) to immediately cancel all speculative requests by setting the byte budget to negative, as shown in the speculative fetching section. This stops further prefetching without affecting in-flight UserInitiated or Background requests.

Question 5

What's the performance impact of Fusillade on Xamarin or MAUI apps?

Accepted Answer

Fusillade can improve performance by reducing redundant network calls and prioritizing requests, but it adds overhead from handler composition and queue management. For bandwidth-constrained mobile apps, the benefits often outweigh costs, but test concurrency settings to avoid UI lag.

Question 6

Can I use Fusillade with .NET Core dependency injection?

Accepted Answer

Yes, Fusillade integrates with Splat for DI, and you can register handlers in your container. For .NET Core DI, manually wire up RateLimitedHttpMessageHandler instances as transient or scoped services, though native integration is limited compared to HttpClientFactory.
