# How to implement Rate Limiting with Polly in .NET applications?

Rate limiting controls the consumption rate of resources by limiting the number of operations that can execute within a specific time frame. This protects downstream dependencies from traffic spikes.

## Using Rate Limiter in Polly v8

Polly v8 integrates directly with `System.Threading.RateLimiting` primitives.

### Code Example

```cs
var rateLimiterOptions = new SlidingWindowRateLimiterOptions
{
    PermitLimit = 100,
    Window = TimeSpan.FromMinutes(1),
    SegmentsPerWindow = 4,
    QueueLimit = 10
};

var pipeline = new ResiliencePipelineBuilder()
    .AddRateLimiter(new RateLimiterStrategyOptions
    {
        DefaultRateLimiter = new SlidingWindowRateLimiter(rateLimiterOptions)
    })
    .Build();

await pipeline.ExecuteAsync(async cancellationToken =>
{
    await SendApiRequestAsync(cancellationToken);
});
```
