support CancellationToken in requests

[drewburlingame]

I have a console app using this library. Querying the list of repositories for one server takes 90 seconds. I can't cancel the command because I can't pass the CancellationToken through the methods. I looked at forking this but there were too many methods for me to update. I ended up with the following workaround. It works but took my a while to determine how to do. Maybe it would even be helpful just to link to an example like this until such time CancellationToken is supported?

        MyHttpClientHandler.CancellationToken = context.CancellationToken;
        FlurlHttp.GlobalSettings.HttpClientFactory = new MyDefaultHttpClientFactory();

        public class MyDefaultHttpClientFactory : DefaultHttpClientFactory
        {
            public override HttpMessageHandler CreateMessageHandler() => (HttpMessageHandler)new MyHttpClientHandler()
            {
                AutomaticDecompression = (DecompressionMethods.GZip | DecompressionMethods.Deflate)
            };
        }

        public class MyHttpClientHandler : HttpClientHandler
        {
            internal static CancellationToken CancellationToken;

            protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
            {
                // ignore the default token
                return base.SendAsync(request, CancellationToken);
            }

            protected override HttpResponseMessage Send(HttpRequestMessage request, CancellationToken cancellationToken)
            {
                // ignore the default token
                return base.Send(request, CancellationToken);
            }
        }

Hey @drewburlingame,

I ran into similar frustrations and ended up creating a modernized fork as an internal solution that I've made publicly available.

BitbucketServer.Net v0.2.0 now has full CancellationToken support across all methods, no more workarounds needed. All async methods accept cancellation tokens that propagate correctly through the entire request pipeline.

Other improvements include:

• ✅ Proper cancellation throughout (no custom handlers required)
• ✅ Modern async patterns with IAsyncEnumerable streaming
• ✅ System.Text.Json for better performance
• ✅ Bitbucket Server 9.0+ compatibility

Cheers,
