IIs 8 Redirect URL from http to https

I have just setuped ssl for my dmain and host. I want to limit my site to https://www.example.com ONLY.

If the any user tried to open http://example.com, www.example.com, example.com or https://example.comhe must be redirected to https://www.example.com

The redirection must be for the domain name only. The rest of any URL would remains as is.

For example: if user opened example.com/dir1/page1.aspx he must be redirected to https://www.example.com/dir1/page1.aspx

I want to do it using IIS rewrite rules.

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

I solved this problem by adding this code to web.config file on the root directory of the domain.

  • First rule matches the url if it isn’t starting with www what ever
    it is http or https
  • second rule matches the url if it is starting with www but it isn’t https

        <rule name="Redirect from non www" stopProcessing="true">
          <match url=".*" />
            <add input="{HTTP_HOST}" pattern="^example.com$" />
          <action type="Redirect" url="https://www.example.com/{R:0}" redirectType="Permanent" />
        <rule name="Redirect from non https" stopProcessing="true">
          <match url=".*" />
            <add input="{HTTPS}" pattern="^OFF$" />
            <add input="{HTTP_HOST}" pattern="^www.example.com$" />
          <action type="Redirect" url="https://www.example.com/{R:0}" redirectType="Permanent" />

Solution 2

Add this in your global.asax file if you donot have control over iis or using a shared hosting where the hosting company doesnt allow u to change the settings.

protected void Application_BeginRequest(object sender, EventArgs e)
    if (HttpContext.Current.Request.IsSecureConnection.Equals(false) && HttpContext.Current.Request.IsLocal.Equals(false))
        Response.Redirect("https://" + Request.ServerVariables["HTTP_HOST"] + HttpContext.Current.Request.RawUrl);


For canonical tag (www.example.com) you dont need to make any changes in your code.
there is a setting given for it in your plesk panel/odin panel (even in shared hosting) to select the default url for you application.

It will automatically redirect your site to www.example.com

The settings in under hosting settings of your website.
select the preferred domain option to www

Note: Use and implement solution 1 because this method fully tested our system.
