"The connection was reset." in chrome based browsers #155

Infiziert90 · 2024-08-28T19:13:00Z

This error happens every time i try to redirect the browser without reading the request body.
Simply calling _ = ctx.Request.DataAsString; before the .Send() fixes it.
Task.Delay(100) didn't fix it on the other hand, so i assume the bug is somewhere in WebserverLite.
Use-case is rate limits without much processing.

Test code:

namespace WatsonLiteTest;

class Run
{
    public static async Task Main(string[] _)
    {
        await new Webserver().Run();
    }
}

class Webserver
{
    private WebserverLite Host;

    public async Task Run()
    {
        Host = new WebserverLite(new WebserverSettings("localhost", 9000), DefaultRoute);

        Host.Routes.PreAuthentication.Static.Add(WatsonWebserver.Core.HttpMethod.GET, "/", AuthRoute);
        Host.Routes.PreAuthentication.Static.Add(WatsonWebserver.Core.HttpMethod.POST, "/auth", AuthenticateClient);
        Host.Routes.PreAuthentication.Static.Add(WatsonWebserver.Core.HttpMethod.POST, "/workingAuth", AuthenticateWorking);

        await Host.StartAsync();
    }

    private async Task AuthRoute(HttpContextBase ctx)
    {
        await ctx.Response.Send("""
