在ASP.NET中，可以使用HttpContext对象及其Response属性将用户重定向到中间件中的其他请求。下面是一个如何实现此目标的示例：

using Microsoft.AspNetCore.Http;

public class MyMiddleware
{
    private readonly RequestDelegate _next;

    public MyMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task InvokeAsync(HttpContext context)
    {
        
        // you can get token or other things that use in authorization from  
        // context and check if you need to redirect it 
        bool shouldRedirect = DetermineRedirectionLogic(context);

        if (shouldRedirect)
        {
            // Perform the redirection
            context.Response.Redirect("/new-url");
            return;
        }

        // If no redirection is required, continue to the next middleware
        await _next(context);
    }

    private bool DetermineRedirectionLogic(HttpContext context)
    {
        // Add your custom logic here to determine if redirection is needed
        // For example, you can check request properties or conditions

        // If redirection is required, return true; otherwise, return false
        return true;
    }
}

在中间件的InvokeAsync方法中，可以在DetermineRedirectionLogic方法中添加自定义逻辑，以根据当前请求确定是否需要重定向。如果需要重定向，可以使用context.response.redirect将用户重定向到其他URL。
确保在Startup类的Configure方法中注册中间件：

public void Configure(IApplicationBuilder app)
{
    // ...

    app.UseMiddleware<MyMiddleware>();

    // ...
}
