Asp.Net switch site to SSL (https) the easy way

For this small article, I assume that you have an Asp.Net web application running on IIS and that you have setup your SSL certificate. So navigating to https://www.yoursite.com works. This blog post will explain how to redirect all http traffic to https in several easy steps.

1. Get the Web Platform Installer (it’s free!) from Microsoft  http://www.microsoft.com/downloads/en/details.aspx?FamilyID=32b0dfe5-f139-4e1c-b412-3da39f50bbf9 

2. After you have opened the WebPI (Web Platform Installer) search for: Rewrite

3. Install the component! [more]

4. Open your web.config (I used notepad++ )

5. Merge this into your web.config:

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

And your done, when you hit save. The IIS will restart if the web.config is modified, so the new rule is now enabled!
