问题描述
我正在尝试为网站实施URL重定向,而不是逐页进行.我想在global.asax文件中执行此操作.下面是我定义的代码.
I am trying to implement URL redirect for the website rather than doing it page by page. I want to do it in the global.asax file. Below is the code i have defined.
我想以 http://website.net 作为我的主要网址&如果有人键入 http://www.website.net ,则希望具有永久的URL重定向.
I want to have http://website.net as my main url & want to have a permanent URL redirect if someone types in http://www.website.net.
很遗憾,它不适用于实时网站.任何人都可以指出代码中的问题.该代码不会产生任何错误.
Unfortunately it is not working for the live website. Can anyone point out the problem in the code. The code doesn't generate any error.
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
if (HttpContext.Current.Request.Url.ToString().ToLower().Contains("http://website.net"))
{
HttpContext.Current.Response.Status = "301 Moved Permanently";
HttpContext.Current.Response.AddHeader("Location", Request.Url.ToString().ToLower().Replace("http://website.net", "http://www.website.net"));
}
}
推荐答案
主要问题:您正在Application_Start
中执行上述操作-仅执行一次.您应该与每个请求挂钩.试试这个:
Main problem: Your're doing the above stuff in Application_Start
- which is only executed once. You should hook up with each request. Try this:
void Application_BeginRequest(object sender, EventArgs e)
{
// Code that runs on every request
if (HttpContext.Current.Request.Url.ToString().ToLower().Contains("http://website.net"))
{
HttpContext.Current.Response.Status = "301 Moved Permanently";
HttpContext.Current.Response.AddHeader("Location", Request.Url.ToString().ToLower().Replace("http://website.net", "http://www.website.net"));
}
}
一种更好的方法是使用URL重写,可以在Web.Config
中进行配置:
An even better approach would be to use URL rewriting, which can be configured from within Web.Config
:
Microsoft重写模块-强制网址上的www或从网址中删除www
