在IIS7中为SEO设置HTTP重定向 [英] Setting up HTTP Redirect for SEO in IIS7

问题描述

我希望所有对 http://mydomain.com 的请求都重定向到

I want all requests to http://mydomain.com to be 301 redirected to http://www.mydomain.com for SEO purposes.

为此，我可以使用IIS7的HTTP重定向方法吗?我尝试将HTTP重定向设置为www.mydomain.com，但这导致了永久循环.

In order to do this, can I use IIS7's HTTP redirect method? I tried setting the HTTP redirect to www.mydomain.com, but this led to a permanent loop.

URL重写将完成这项工作，除非有人有更好的主意，否则我将使用它:

URL Rewrite will do the job, and I am going to use it, unless somebody else has a better idea:

有什么建议吗?

推荐答案

使用IIS7可能有一种方法.诀窍在于提供防止无限循环的条件.不幸的是，我不确定该怎么做.

There probably is a way to do this with IIS7. The trick would be in providing a condition to prevent the infinite loop. Unfortunately I'm not sure how to do that exactly.

但是您也可以在.NET代码中非常轻松地执行此操作，因为我正在执行相同的操作.我只是将其放在您的Global.asax中:

But you can also do this in .NET code very easily as I'm doing the same thing. I'd just put this in your Global.asax:

Imports System.Web.HttpContext
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
  Dim strWebsite As String = "http://www.mydomain.com"

  If Not Current.Request.Url.AbsoluteUri.StartsWith(strWebsite) Then
    Current.Response.Clear()
    Current.Response.Status = "301 Moved Permanently"
    Current.Response.AddHeader("Location", strWebsite & Current.Request.RawUrl)
    Current.Response.End()
  End If
End Sub
