I need to redirect my Http site to HTTPS, have added below rule but I am getting 403 Error when tried using http://www.example.com, it working fine when I type https://www.example.com in browser.

<system.webServer>
<rewrite>
<rules>
<rule name="HTTP to HTTPS redirect" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" />
</rule>
</rules>
</rewrite>

Answer

You can do it in code:

Global.asax.cs

protected void Application_BeginRequest(){
    if (!Context.Request.IsSecureConnection)
        Response.Redirect(Context.Request.Url.ToString().Replace("http:", "https:"));
}

Or You could add the same code to an action filter:

public class SSLFilter : ActionFilterAttribute {

    public override void OnActionExecuting(ActionExecutingContext filterContext){
        if (!filterContext.HttpContext.Request.IsSecureConnection){
            var url = filterContext.HttpContext.Request.Url.ToString().Replace("http:", "https:");
            filterContext.Result = new RedirectResult(url);
        }
    }
}
