A .NET Standard Library to bypass Cloudflare's Anti-DDoS measure (JavaScript challenge) using a [DelegatingHandler](https://msdn.microsoft.com/en-us/library/system.net.http.delegatinghandler(v=vs.110).aspx).

## Features
- No dependencies (e.g. no external JavaScript interpreter required)
- Easily integrated into your project (implemented as DelegatingHandler; e.g. can be used with [HttpClient](https://msdn.microsoft.com/en-us/library/system.net.http.httpclient(v=vs.118).aspx))
- Usable on many different platforms ([NET Standard 1.1](https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.1.md))

## Usage
```csharp
try
{
    // Create the clearance handler.
    var handler = new ClearanceHandler
    {
        MaxRetries = 2 // Optionally specify the number of retries, if clearance fails (default is 3).
    };

// Create a HttpClient that uses the handler to bypass CloudFlare's JavaScript challange.
    var client = new HttpClient(handler);

// Use the HttpClient as usual. Any JS challenge will be solved automatically for you.
    var content = await client.GetStringAsync("http://protected-site.tld/");
}
catch (AggregateException ex) when (ex.InnerException is CloudFlareClearanceException)
{
    // After all retries, clearance still failed.
}
catch (AggregateException ex) when (ex.InnerException is TaskCanceledException)
{
    // Looks like we ran into a timeout. Too many clearance attempts?
    // Maybe you should increase client.Timeout as each attempt will take about five seconds.
}
```
