视图不更新

Question

我有一个这样的view：

<div class="container content-sm">
    @{
        if (Request.IsAuthenticated)
        {
            <a>my profile</a>
        }
        else
        {
            if (Request.Url != null)
            {
                <a>Log in</a>
            }
        }
    }
<div class="row">
    <div class="col-md-9">
        <div class="blog-item">
            some html tags ...
        </div>
        <div>
            <a>Next article</a>
        </div>
        <script type="text/javascript" src="~/Scripts/jquery-1.10.2.min.js"></script>
        <script type="text/javascript" src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
        <div class="post-comment hidden-print" id="comment-tool-box">
            @using (Ajax.BeginForm("SaveComment", "News", new { id = Model.Blog.Id }, new AjaxOptions
            {
                HttpMethod = "POST",
                UpdateTargetId = "CommentToolPanel",
                LoadingElementId = "loader",
                OnBegin = "OnBegin",
                OnSuccess = "OnComplete",
                OnFailure = "OnFailure"
            }, new {@class = "my-form"}))
            {
                @Html.AntiForgeryToken()
                @Html.Partial("_PartialComment")
            }
        </div>
    </div>
</div>

和controller:

    [Route("en-us/blogs/explore/show/{year}/{month}/{day}/{id}/{title}")]
    public ActionResult Details(string year, string month, string day, int id)
    {
        try
        {
            var model = _db.Table.ToList();
            return View(model);
        }
        catch (Exception exception)
        {
            _logger.Log(exception);
            return View("Index");
        }
    }

    public string Captcha(int id)
    {
        Response.Cache.SetCacheability(HttpCacheability.Public);
        Response.Cache.SetMaxAge(new TimeSpan(0, 5, 0));
        var obj = new RandomStringGenerator(true, true, true, false)
        {
            MinLowerCaseCharacters = 2,
            MinNumericCharacters = 2,
            MinUpperCaseCharacters = 2
        };
        var input = obj.Generate(7);
        var bmp = new Bitmap(1, 1);
        var graphics = Graphics.FromImage(bmp);
        var font = new Font("Arial", 20f);
        var stringSize = graphics.MeasureString(input, font);
        bmp = new Bitmap
            (
            bmp,
            (int)stringSize.Width,
            (int)stringSize.Height
            );
        graphics = Graphics.FromImage(bmp);
        graphics.DrawString(input, font, Brushes.LightGray, 0, 0);
        font.Dispose();
        graphics.Flush();
        graphics.Dispose();
        var width = bmp.Width;
        var height = bmp.Height;
        var tmp = new Random();
        for (var x = 0; x < width; x++)
        {
            for (var y = 0; y < height; y++)
            {
                var r = tmp.Next(0, 255);
                var g = tmp.Next(0, 255);
                var b = tmp.Next(0, 255);
                bmp.SetPixel(x, y, Color.FromArgb(255, r, g, b));
                y++;
            }
            x++;
        }
        MemoryStream stream;
        using (stream = new MemoryStream())
        {
            bmp.Save(stream, ImageFormat.Png);
        }
        var image = stream.ToArray();

        var imageBase64Data = Convert.ToBase64String(image);
        var imageDataUrl = $"data:image/png;base64,{imageBase64Data}";
        var captchaImage =
            $"<a data-ajax=\"true\" data-ajax-mode=\"replace\" data-ajax-update=\"#capt1\" href=\"/News/Captcha\"><img src='{imageDataUrl}' title=\"Click to reload a new image\" /></a>";

        System.Web.HttpContext.Current.Session["maCaptcha"] = input;

        Session["maCaptcha"] = input;

        return captchaImage;
    }

和_PartialComment查看

<div id="CommentToolPanel" class="hidden-print">
<header>Leave a Comment</header>
<fieldset>
    <section>
            @{
                var opts1 = new AjaxOptions
                {
                    UpdateTargetId = "capt1"
                };
            }
            <span id="capt1">
                @Html.Action("Captcha", "News")
            </span>
            @Html.TextBoxFor(m => m.CaptchaString, new
            {
                id = "captchaImage",
                name = "captchaImage",
                type = "text",
                placeholder = "Captcha code is case censitive."
            })
    </section>
</fieldset>
<footer>
            <button type="submit" class="button" id="btnComment">Submit</button>
</footer>

第一次加载视图时，一切都很好，但是，当我刷新浏览器时，控制器中的Details 方法不会触发，但是页面的内容会更新。
假设数据库中有 2 条记录。第一次显示记录#1（到目前为止还不错），点击下一步，记录#2也会显示（似乎很好），现在，我尝试再次显示记录#1，它会，但是Details方法没有被触发。
所以，我的问题是：如果用户登录并浏览该页面，然后注销然后返回该页面，我的个人资料链接仍然显示，因为，视图未更新。
我试试这些东西：
ASP.NET MVC AjaxForm not updating partial view properly
Update A Div And Partial View Using Ajax.BeginForm On Form Submit
[Walkthrough] Updating Partial Views with Unobtrusive AJAX in MVC 3
View not updating after post
但没有帮助:(

编辑：
当我从 _PartialComment 视图中删除这部分代码时，问题将得到解决： @Html.Action("验证码", "新闻") @Html.TextBoxFor(m => m.CaptchaString, 新 { id = "验证码图像", 名称=“验证码图像”， 类型=“文本”， placeholder = "验证码区分大小写。" })

你能告诉我我的错误是什么，哪些部分是错误的？
我该如何解决这个问题？

Answer 1

通过在Captcha 方法中删除这些行，我的问题就解决了！！！

    Response.Cache.SetCacheability(HttpCacheability.Public);
    Response.Cache.SetMaxAge(new TimeSpan(0, 5, 0));

我不知道为什么。
