Question

我正在运行计时器并在用户更改其密码后执行重定向（AKA，通知他们密码已更改，然后将其发送回主页）。但是，我似乎无法在下面的代码中执行相对路径。下面列出了我喜欢做的事情：

Response.AddHeader("REFRESH", "2;URL="~/pages/home.aspx");

为什么这不起作用？我如何让它工作？（我知道我可以在网站的其他部分做相对路径，但这是因为它正在运行服务器端。）谢谢。

您需要为REFRESH标头指定绝对URL。看一下this post，了解如何从亲戚那里获取绝对网址（你可以使用那里显示的ResolveServerUrl）：

Response.AddHeader("REFRESH", "2;url=" + ResolveServerUrl("~/pages/home.aspx"));

供参考：

/// <summary>
/// This method returns a fully qualified absolute server Url which includes
/// the protocol, server, port in addition to the server relative Url.
/// 
/// Works like Control.ResolveUrl including support for ~ syntax
/// but returns an absolute URL.
/// </summary>
/// <param name="ServerUrl">Any Url, either App relative or fully qualified</param>
/// <param name="forceHttps">if true forces the url to use https</param>
/// <returns></returns>
public static string ResolveServerUrl(string serverUrl, bool forceHttps)
{
    // *** Is it already an absolute Url?
    if (serverUrl.IndexOf("://") > -1)
        return serverUrl;

    // *** Start by fixing up the Url an Application relative Url
    string newUrl = ResolveUrl(serverUrl);

    Uri originalUri = HttpContext.Current.Request.Url;
    newUrl = (forceHttps ? "https" : originalUri.Scheme) + 
             "://" + originalUri.Authority + newUrl;

    return newUrl;
} 

/// <summary>
/// This method returns a fully qualified absolute server Url which includes
/// the protocol, server, port in addition to the server relative Url.
/// 
/// It work like Page.ResolveUrl, but adds these to the beginning.
/// This method is useful for generating Urls for AJAX methods
/// </summary>
/// <param name="ServerUrl">Any Url, either App relative or fully qualified</param>
/// <returns></returns>
public static string ResolveServerUrl(string serverUrl)
{
    return ResolveServerUrl(serverUrl, false);
}

Response.AddHeader的相对路径
