IIS URL Rewrite

This IIS extension provides the ability to create rewrite rules, ie: HTTP and HTTPS. Read more here. Start by downloading and install the URL Rewrite Module for IIS.

In this example, we will create a HTTPS redirect rule:

1. Under IIS snap-in, Untick 'Require SSL' under [SSL Settings] for the desired site or for the 'Default Web Site' if the site falls under it
   
   
2. Open [URL Rewrite] > under 'Inbound rules select [Blank rule] > OK
   
   
3. Under 'Match URL' option, leave [Match the Pattern] under 'Required URL' and [Regular Expressions] under 'Using' as default. Under 'Patterns', enter .* and leave 'Ignore case' ticked
   
   
4. Under 'Conditions', leave [Match All] > [Add] to define the following;
   
   
   Input = {HTTPS}
   Type = Match the Pattern
   Pattern = OFF
5. Under 'Action', define the following:
   
   Action type = Redirect
   Redirect URL = https://{HTTP_HOST}/{R:0}
   Select 'Append query string' checkbox
   Redirect type = Permanent (301)

This will apply the configuration automatically. The above creates the following in the web.config;

<system.webServer>

    <rewrite>

        <rules>

            <rule name="HTTP to HTTPS redirect" stopProcessing="true">

                <match url=".*" />

                <conditions>

                    <add input="{HTTPS}" pattern="OFF" />

                </conditions>

                <action type="Redirect" url="https://{HTTP_HOST}/{R:0}" redirectType="Permanent" />

            </rule>

        </rules>

    </rewrite>

</system.webServer>
